President Barack Obama will travel to Aurora, Colo., on Sunday to see victims of the movie theater shooting and families of victims, White House officials said.

Obama will not attend a vigil planned there for Sunday but will continue on to San Francisco, the officials said. He also will meet with local officials in Aurora.

In his weekly radio address, Obama called for prayer and reflection on the shooting rampage in Aurora, Colo., which claimed 12 lives. He urged Americans to embrace the families who lost loved ones in Aurora and to "let them know we will be there for them as a nation."

Twelve people were killed and 58 injured when a gunman opened fire early Friday at a midnight showing of "Batman: The Dark Knight Rises." James Eagan Holmes was arrested after the shooting and is being held in solitary confinement.
