Newt Gingrich will make his first appearance with presumptive GOP nominee Mitt Romney on May 29 in Las Vegas.

NBC News has learned the former House speaker will attend a fundraiser for Romney at Trump Towers in Las Vegas Tuesday evening. Donald Trump will also attend.

The last time Gingrich and Romney were in Nevada together was in early February, amid a bitter fight for the nomination.

Rumors broke just days before the Feb. 4 Nevada caucuses – and were confirmed by several news outlets -- that Trump himself would endorse Gingrich. Hours later, however, the casino mogul endorsed Romney.

A joint public event with the two former competitors may occur next month.

MOORESVILLE, NC -- Even though his presidential campaign "will go bye-bye," Newt Gingrich on Thursday said he and his wife plan to campaign through the fall to help presumptive nominee Mitt Romney.

"I'm going to look at how I can be helpful, because I suspect people will still show up to hear me," Gingrich told voters at luncheon here. "Callista and I are going to campaign through October."

Though today, just 25 people attended the midday event here, leaving a roomful of empty chairs. Some of those seats were taken by Secret Service, an area the campaign has taken heat for recently because of the thousands of dollars the protection was costing taxpayers, even Gingrich he had become more of a sideshow than serious contender for the GOP nomination.

After losing the Deleware primary on Tuesday, the latest in a long string of electoral defeats, the former Speaker of the House acknowledged he will end his campaign next week. He will continue with his packed schedule through North Carolina, saying he felt an obligation to fulfill previous commitments here.

"The campaign will go bye-bye, but I'll be a citizen," Gingrich told a supporter asking about the candidate's future. "I've been an active citizen since I was 15."

The once top-tier GOP candidate said he would welcome the opportunity to stump for former rival Romney. He has spoken to the former Massachusetts governor and Republican National Committee Chair Reince Priebus about playing a role in the party going forward. At a stop at a diner here this morning, Gingrich continued his pledge to forge ahead to the summer convention in Tampa -- only now, as a citizen and not a candidate.

"We're also going to go back to the private sector to earn some money," Gingrich said. "It's been a long, expensive 2 years."

Gingrich's now-bare-bones campaign faces deep debts; he had previously been a paid contributor to FOX News, but criticized his former employer, saying he could get a fairer shake from CNN; and his flagship company, The Gingrich Group, filed for Chapter 7 bankruptcy earlier this year.

"I ran for president and, candidly, wished I had done better," Gingrich said Thursday morning. "But I learned a lot."

And while the former frontrunner says he's eager to help, it likely will not be on the Romney ticket. "I think the vice president will be somebody much younger," Gingrich said. "That would be my advice to Romney."

BALTIMORE, MD -- Newt Gingrich considers himself a man of “really big ideas” and has used his presidential run to share them with thousands of Americans.

The former House speaker faced criticism from opponents for being “grandiose,” which prompted Gingrich to respond in January: “I accept the charge that I am grandiose and that Americans are instinctively grandiose."

While Gingrich continues fighting the increasingly uphill battle of trying to become the Republican nominee, here is a recap of some of the more fantastical ideas he has thrown out over the past 10 months of the campaign.

CREATING A MOON COLONY

DESTINY IN SPACE
“I want to restate, far from backing off, I want to restate, America has a destiny in space. It is a part of who we are. We are not going to back off from John Kennedy’s challenge and we are not going to go timidly into the night allowing the Chinese to dominate the future of space.” – Huntsville, AL 3.6.12

SEND PACKAGE TO ILLEGALS
“UPS and FedEx move twenty four million packages a day and track them in virtually real time. Over here is the federal government, the world that fails. And let me give you an example of what I’m talking about: twenty four million packages tracked while they move; eleven million illegal visitors sitting still. Or 15 million. One of my proposals is very simple. We send a package to every person who’s here illegally. When it’s delivered, we pull it up, we know exactly where they are. It’s on the computer.” – Council Bluffs, IA 11.30.11

NATIONAL SECURITY
“You think about an Iranian nuclear weapon.  You think about the dangers – to Cleveland, or to Columbus, or to Cincinnati, or to New York.   Remember what it felt like on 9/11 when 3100 Americans were killed.  Now imagine an attack where you add 2 zeros.  And it’s 300,000 dead.  Maybe a half million wounded.  This is a real danger.  This is not science fiction.  That’s why I think it’s important that we have the strongest possible national security.” – Cleveland, OH 2.8.12

CHANGE ALL OF AMERICA
“You have a bipartisan establishment that has been running this country, that has created a gigantic mess.  You have bureaucracies that are out of control, judges who think they can be dictators.  You have systems around this country.  You have laws that don’t work.  So, we have got to change not just Obama, we have got to change the entire direction of the United States of America to get it back on track and that is our obligation to these young people." – Rock Hill, SC 1.11.12

HOW TO FIX GAS PRICES
“The long-term answer is American’s producing their own energy and telling other people, ‘you may have a problem, we don’t because we can be the largest oil producer in the world by the end of this decade. Bigger than Russia, bigger than Saudi Arabia. We have vastly more resources than any other country if we use them.” – San Francisco, CA 2.25.12

AFGHANISTAN
“We’re not going to fix Afghanistan.  It’s not possible…There’s some problems where what you have to do is say, ‘You know, you’re going to have to figure out how to live your own miserable life because I’m not here – you clearly don’t want to hear from me how to be unmiserable.’  And that’s what you’re going to see happen.” – Nashville, TN 2.27.12

ISLAMIC WORLD
“I believe we need to reassess every element of our relationship with the Islamic world and we need to be prepared to do whatever it takes to become economically independent and to be able to tell the truth. And American president who cannot tell the truth cannot possibly defend this country.” – Rome, GA 2.28.12

MEET WITH DEMOCRATS AND PUT THEM IN GROUPS
”Between the election and the inauguration, I will try to meet with every Democrat individually and sit down with them face to face and say look I’m going to be here for four years and what is it that you’re trying to get done that’s compatible with what I’m trying to get down. Now, they’ll break down into three groups. There will be the crazies. We won’t invite them back. There will be hardheaded guys who you can get occasionally. And there will be folks who say I’m glad we’re trying to do this together, let’s see what we can get done.” – Mobile, AL 3.10.12

PAY-PER-VIEW DEBATE
”Let me just say to the president: I will be glad to debate him anywhere, any time, and I’ll go a step further just to make it non-political. We ought to debate on pay-per-view and we ought to charge ten bucks to watch the debate, and it ought to go to a charity of our mutual choice, and it would be the largest charity fundraiser in the country this year. And the topic ought to be price of gasoline.” – Shreveport, LA 3.20.12

ATTITUDE OF MODERN WORLD
“The psychological attitude of the modern world is such that if Thomas Edison invented the electric light in the modern era, it would be reported on the network news as the candle making industry was threatened today. And somebody on the left would jump up and say this was all an excuse for killing poor people by putting electricity in their homes, and who knows what the electricity will do to them. And is this really a gamble to electrocute people? Think about -- Everything we do nowadays is negative.” – Frederick, MD 4.2.12

OBAMA/BIRTHDAY CAKE RECIPE
“If you went to somebody who was a great cook and you said ‘do you think you can bake a birthday cake’ and they said ‘sure I can bake a birthday cake,’ the odds are pretty high they’ll be able to bake a birthday cake. Now it helps to have a recipe for birthday cakes and it helps to have baked one. President Obama’s biggest challenge is, that he has exactly the wrong ideas. He belongs to an ideology that believes the way you get hard eggs is you freeze them (laughs)…. This is his whole problem with job creation.” – Dyersville, IA 12.27.11

FOOD STAMPS
“And so I’m prepared, if the NAACP invites me, I’ll go to their convention to talk about why the African American community should demand pay checks and not be satisfied with food stamps. And I’ll go to them and I’ll explain a brand new social security opportunity for young people, which would be particularly good for African American males, because they’re the group that gets the smallest return on social security…” – Plymouth, NH 1.5.12

PAY KIDS TO WORK
“You have a very poor neighborhood. You have kids who are required under law to go to school. They have no money, they have habit of work. But what if you paid them part time in the afternoon to sit in the clerical office and greet people that came in. What if you paid them to work as the assistant librarian? And I’d pay them as early as was reasonable and practical. And then we get into the janitor thing. These letters were written saying janitorial work is really hard and really dangerous. Fine. So what if they became assistant janitors and their job was to mop the floor and clean the bathroom and you pay them?” – Des Moines, IA 12.1.11

BEAR ARMS IN OUR TRUCKS
“You can’t put a gun rack in a Volt. So, let’s be clear what this election is all about. We believe in the right to bear arms and we like to bare the arms in our truck, there.” – Peachtree City, GA 2.17.12

NOT BOW TO SAUDI KING
“If you would like to have a national American energy policy, never again bow to a Saudi king and pay $2.50 a gallon, Newt Gingrich will be your candidate.” – San Francisco, CA 2.25.12

IRAN
“We should indicate calmly and decisively that any act to close the Straits of Hormuz will be considered an act of war and we will eliminate the government of Iran.” – Knoxville, TN 3.5.12

IMMIGRATION
“I think the vast majority of them should go home. And we should be very clear about this. If you are here without any great ties to the United States and you came here illegally, you just need to leave and apply for the guest worker program from back home. Period…I do think that if you have somebody in your neighborhood who has been here for 25 years, and they belong to your church and they have three kids and two grandkids, and they have been paying taxes and working hard the entire time, it’s going to be very, very hard to get the American people to agree that we should tear up those families and expel them.” – Naples, FL 11.25.11

COURTS
“I do think it’s legitimate for the Congress and the president to address the 9th circuit’s aggressive anti-religious bias but I think that will be done with other methods. I’d ask the Congress to look seriously at either impeaching or replacing the 9th circuit.” – South El Monte, CA 1.15.12

GINGRICH TREATY
“I proposed yesterday what Chris Cox of the NRA called the Gingrich Treaty. As president, I would propose that the United States submit a treaty that says that the right to bear arms is a universal human right and that every human being on the planet should have the right to bear arms. That the Second Amendment should apply everywhere." – Raleigh, NC 4.14.12

BRAIN SCIENCE RESEARCH
"The number of things we'll learn by learning about the brain will absolutely pay for itself probably by a thousand to one or better. Literally in terms of cost to the government … This is a very big idea in an area that I don't know of any political leader who is willing to tackle that would lead to a dramatic explosion of new science that would lead directly to a better quality outcome for health which would lower the cost of healthcare which would help solve our long term budget problems and would create a huge new zone of creating American jobs. But it requires having a conversation in an area the people just aren't used to talking about politically.” – Iowa City, IA 12.14.12

WASHINGTON, DC — Newt Gingrich's campaign is laying off a third of its paid staff, replacing its campaign manager, and lightening the campaign schedule as he continues with poor finishes in elections and is receiving little incoming money for his campaign.

“The campaign is being redesigned to focus on Tampa,” campaign spokesman R.C. Hammond told NBC News.

News of the cutbacks were first reported by Politico Tuesday evening. 

Michael Krull, an Iowan and college friend of Gingrich’s wife, Callista, who took over as campaign manager shortly after most of Gingrich’s original staff ditched him last summer, agreed to resign his position last weekend. Now, Vince Haley, the current deputy campaign manager and policy director, will assume the role.

Hammond refused to comment on what other staff were let go, saying “he will not discuss personnel matters.”

Gingrich’s campaign has been struggling to stay afloat financially for several weeks — posting slightly more debt than cash on hand in the last FEC filing for February. The former House Speaker, though, continues to promise he will go all the way to the Republican convention in Tampa this August unless another candidate obtains all 1,144 delegates beforehand.

Asked earlier today while campaigning in Maryland if he realistically has enough money to last him until the summer, Gingrich said he does.

“The money is very tight obviously,” he told reporters outside the state house.

The speaker even alluded to this apparent staff shake up, as well.

When asked by reporter in Annapolis this morning if he was asking his staff to take pay cuts, Gingrich said: “Well we're working through what it is going to take to get there [to the convention] and I think probably Joe DeSantis or R.C. will have something to say about that in the next day or two.”

Gingrich typically holds anywhere from three to five public campaign events a day but on Wednesday, Gingrich only has one public event scheduled in Washington, D.C. This trend will continue for the campaign as they begin to lighten the number of events.

Communications director Joe DeSantis tells NBC News as far as cutting back travel, “You will see Newt spend longer stretches of time in key states rather than bouncing from state to state.”

The speaker was originally scheduled to spend Wednesday in North Carolina but then cancelled the trip just yesterday.

These shakeups will undoubtedly increase speculation and calls for Gingrich to exit the GOP race. He has only won two states — his home state of Georgia and South Carolina — and is trailing both Mitt Romney and Rick Santorum in the delegate count.

CHICAGO, IL -- Newt Gingrich prides himself in running an unconventional presidential campaign and the man who currently oversees the team’s daily operations of that campaign fits this “anti-establishment” mold perfectly.

Patrick Millsaps, 39, Gingrich’s chief of staff, explains that he “stumbled into working in politics” a few years ago. He was brought on as the campaign’s top aide in late December amid an implosion in Gingrich’s numbers heading into the Iowa caucuses – the first contest that would launch two and a half months of voting.

“I got involved in politics by happenstance; I needed a job out of college,” said Millsaps, who graduated from Samford University in 1995 with a degree in Psychology after a short stint as a preacher. (He remains a licensed Baptist Minister who can still marry and bury people.)

Growing up in Marietta, GA, Millsaps was a constituent of the Republican lawmaker who would become his future boss – former House Speaker Gingrich. But the two men only met once, in 1994, as Gingrich worked the ropeline following an event. Eighteen years later, Millsaps, a lifelong Georgian, made his interest in helping the campaign known.

“The one type of race I have never been involved in as a volunteer was a presidential race,” Millsaps recalls telling one of Gingrich’s close advisors, Randy Evans, in early 2011. “I told him if there is ever a way I can help in a meaningful way, let me know.”

Nine months later, Evans did just that. Millsaps was contacted by the Gingrich campaign the day after Christmas (as he was about to take a week vacation), and flew to Iowa first thing to start as deputy legal counsel.

“One day he was in a court room in Southern Georgia, the next he was smack in the middle of the GOP primary. He didn’t blink,” Gingrich spokesman R.C. Hammond said.

Having graduated from the University of Georgia School of Law in 2000, Millsaps has been practicing law ever since.

“In 1996, I worked as a deputy political director for a United States Senate candidate in Georgia,” he said. “I decided to go to law school after we lost the primary and after that I decided I was just done with politics.”

Moving to Camilla, GA – a small town in the Southwest section of the state – back in 2004, Millsaps started his own law practice while his wife, Elizabeth, opened a pharmacy. He continued to stay active in politics here and there, helping his former law school friends organize events for politicians near him, while also raising his three small daughters.

After working with the Gingrich campaign for just more than a month, the speaker promoted Millsaps to chief of staff when their charter plane landed in Reno, NV in early February. In this new role, Millsaps changed the organizational structure of the campaign and even created internal teams to help the process flow better.

“I think I brought a perspective that was very non-DC – there is nothing further from Washington, D.C. than Southwest Georgia,” he said.

This is the type of campaign Gingrich is trying to run, according to Millsaps, who admitted he thought he would be off the campaign after South Carolina. “It has been a benefit that I have worked on enough campaigns that I know my way around campaigns but it has also been a benefit that I bring a different perspective to the table,” he said.

“Patrick has really done a great job at doing a lot with limited resources in such a short amount of time,” Hammond said.

Now, Millsaps and the speaker work together very closely every day and have even become friends, complementing each other with their traits along the way.

“Speaker Gingrich is the one who came up with $2.50 gasoline. Nobody saw gasoline as the big issue. He has the big idea of how he wants his campaign to go and what we need to be talking about and then I am the one who tries to figure out what kind of assets we have and how we get the message out,” Millsaps said.

Millsaps described himself as the campaign’s “problem solver” and noted that the campaign always had a great product in its candidate – they just needed someone to push that material out the door to voters.

Vowing to only work for politicians he truly believes in, Millsaps says Gingrich has really struck him as a different type of politicians and doesn’t see this type of campaign happening again.

“Newt is the most intellectually curious person I have ever met,” he said. “I have met a lot of politicians that are just so full of themselves that you will never get a word in edgewise but Newt is the opposite of this.”

No matter what happens in the next few weeks, the chief of staff says he is in for the long haul.

“I am one of these people who believes that God has a plan for me and I am just going to see what happens next. I will stay with the campaign and hopefully take it all the way to Tampa and then see what happens,” Millsaps said. “I learned a long time ago that the people who try to plan their lives out seem to be disappointed.”

Despite winning just one state last night, Newt Gingrich is vowing to stay in the race.

"We are staying in this race, because I believe it is going to be impossible for a moderate to win the general election," Gingrich said.

He dismissed Rick Santorum as a "good team member," but one who can't change the game.

"With all respect to my friend from Pennsylvania, Sen. Santorum," Gingrich said, "there is a big difference between being a good team member and changing the game."

The comments are similar to what Gingrich said this morning on Bill Bennett's "Morning in America" radio show.

"If I thought he was a slam dunk to beat Romney and to beat Obama, I would really consider getting out," Gingrich said of Santorum on the show. "I don’t ... I think each of the three candidates has strengths and weaknesses and that this is a very healthy vetting process.”

Gingrich refused to set the bar of when he might drop out.

"If you asked Rick Santorum that question immediately after Nevada, what would we have said?" Gingrich retorted. "He had been running fourth for a month and -- including me -- people were saying maybe he should drop out. He ignored all those. He now has had a terrific month. I think you have to wait and see how the race goes on.”

Newt Gingrich threatened Monday to skip any debate as the Republican nominee versus President Obama that's moderated by a member of the media.

"As your nominee, I will not accept debates in the fall in which the reporters are the moderators," Gingrich said at a rally in Pensacola. "We don’t need to have a second Obama person at the debate."

The threat is in keeping with the scorn with which the former House speaker has treated the press throughout the campaign, particularly at debates. Gingrich most notably won a standing ovation by angrily dismissing a question at a South Carolina debate having to do with extramarital allegations made by an ex-wife.

Moreover, Gingrich has made his debating prowess a central selling point of his candidacy, promising fantastical showdowns with Obama in the general election. A frequent applause line for Gingrich, for instance, is his promise to challenge the president to seven, three-hour Lincoln-Douglas style debates.

As a reminder, though, presidential debates are governed by the Commission on Presidential Debates, which have organized the general election debates since 1998. The commission has already set the number of presidential debates in 2012 at three, slated for this October. The moderators in these debates have not been announced, but will almost certainly be members of the media.

DORAL, FL -- Newt Gingrich combined attacks on Mitt Romney's wealth and his stance on immigration in a forum less than a week before the Latino-heavy Florida GOP primary.

Gingrich attacked the former Massachusetts governor for being out-of-touch with the experience of undocumented immigrants in the U.S. who have laid down roots in America.

"I think you have to live in worlds of Swiss bank accounts and Cayman Island accounts and automatic $20 million a year income with no work to have some fantasy this far from reality," Gingrich said at a forum organized by the Spanish-language network Univision. "I talk very specifically about people who have been here for a long time ...for Romney to believe that somebody's grandmother is going to be so cut off she is going to self deport? This verges -- this is an Obama level fantasy."

Gingrich defended his immigration policy while criticizing his chief rival’s policy for lacking “humanity” and being a “fantasy.”

“He certainly shows no concern for the humanity of the people who are already here,” Gingrich told the crowd about Romney, who floated the idea of self-deportation in a Republican debate on Monday night, a concept somewhat nebulous in its execution.

The former House speaker, who began his interview with Univision anchor Jorge Ramos, believes that citizen panels should decide if illegal immigrants who have been in the United States for 20-25 years and participate in the community should be allowed to remain in the country legally. Gingrich wants to build a new worker permit program, as well.

The speaker continued to stump in one of the most heavily Hispanic parts of Florida today giving a speech on Latin American Policy at Florida International University.

Gingrich made his case for why he's best suited to win over Latinos in the general election. He said he aims to win 50 percent of Latinos nationally and outlined policy positions that might contribute to him making inroads in that community

But Gingrich trails Romney among Latinos voting in next Tuesday’s primary according to a new poll, and performs more poorly than Romney against Obama among Latinos nationally.

A new poll conducted by Latino Decisions for Univision News and ABC News finds that Romney holds a 15 percent lead over Gingrich in the Hispanic vote in Florida, 35 to 20 percent.

Both presidential candidates are courting voters in the Miami area today.

Ramos asked Gingrich to clarify comments he made in 2007 where it seemed he implied that Spanish was the language of the ghetto. 

"It wasn't about Spanish, I said it about all languages," Gingrich said inside the Univision studios.

"I am for English as a common unifying language…Most parents, whatever their linguistic background, want their children to be able to function in English because they know they will have a better job and a better future,” he said.

The speaker, whose oldest daughter lives in Miami-Dade county, even got a little chocked up at his speech at FIU while talking about his granddaughter learning to play the violin by a Cuban-American violinist -- Luis Haza -- who escaped from Fidel Castro’s rule after his father was executed.

“If you talk to Luis, you will understand the passion that he is left here to deal with over the years and why my determination to free Cuba and to help the people of Cuba be free is because he is a deep, deep advocate for human freedom and decency,” Gingrich said about Haza.
