Darrell Issa Richest Man in Congress

Worth $355 million

The chief inquisitor of President Obama's White House is now Congress's richest man.

House Oversight Committee Chairman Darrell Issa (R-Calif.) saw his fortune rise to at least $355 million in 2012, enough to take the crown on The Hill's 50 Wealthiest list.

Issa, who made his riches with the Viper car security system, snatched the No. 1 spot away from Rep. Michael McCaul (R-Texas), who came in second with a net worth of at least $101 million.
