Members of Congress have pushed more than $300 million in earmarks and other provisions to projects near their own properties, the Washington Post reported on Tuesday.

Thirty-three members of Congress channeled the public funds into projects next to or within two miles of properties they own, according to the newspaper's investigation.

The Post said this is legal under ethics rules penned by lawmakers themselves.

The investigation into the holdings of all 535 members also revealed that 16 had steered federal funds to firms, colleges and programs where family members worked or sat on boards, the newspaper reported.

In one case, an Alabama senator directed more than $100 million in federal earmarks to upgrade an area near his office building in Tuscaloosa, according to the Post. Another representative reportedly earmarked $486,000 to build a bike lane to a bridge near a property she owned. (Click here for full results of the Washington Post investigation)
