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.
Overall, the Republican Party has the edge on The Hill's list for the third year in a row, with 29 of the 50 lawmakers coming from the conservative side of the aisle.
Thirty-seven of the lawmakers on the list are from the House, with the remaining 13 coming from the Senate.

Ex-Sen. Herb Kohl (D-Wis.), owner of the NBA's Milwaukee Bucks and another regular on the list, decided to retire after last year's election.
And the late Sen. Frank Lautenberg (D-N.J.), who was the first full-time salesman for the payroll processing company Automatic Data Processing, died in 2013.
Taking their place are several lawmakers who are serving their first terms on Capitol Hill.
Among the new additions is Rep. Joseph Kennedy (D-Mass.), whose $15.2 million showing continues the tradition of having a wealthy member of the Kennedy clan in Congress.

Other lawmakers earned a spot on the list after their assets climbed skyward.
Rep. Jim Cooper (D-Tenn.) saw his share in Kentucky and Tennessee farmland and real estate spike, helping to give him a net worth of $8.2 million. Rep. John FlemingJohn Calvin FlemingLobbying world Trump wants Congress to delay Census deadlines amid pandemic Meadows sets up coronavirus hotline for members of Congress MORE's (R-La.) wealth was $10.7 million in 2012 after his holdings in franchise development and properties soared in value.
But it's Issa who stands as king of Capitol Hill, thanks in no small part to the removal of $100 million in liabilities from his balance sheet on his 2012 form.
Issa listed several investment funds among his assets, including some that are worth more than $50 million each. He also has properties valued in the millions of dollars.
Before coming to Congress, Issa was a successful chief executive who founded Directed Electronics and served as chairman of the Consumer Electronics Association.
The runner-up on the list, McCaul, owes much of his wealth to family trusts. His wife, Linda, is the daughter of Clear Channel Communications founder Lowry Mays.
To come up with its rankings, The Hill used financial disclosure forms covering the 2012 calendar year. The reports are not perfect because they provide value ranges instead of exact figures.
The Hill adds up the low figures in each value range for every asset and liability. Then, the sum of a lawmaker's liabilities is deducted from the sum of his or her assets to calculate a minimum net worth.
Some lawmakers provide lengthy bank statements or investment reports with their annual financial statements. The Hill uses exact figures when possible.
The methodology is designed to provide a conservative estimate of a lawmaker's worth, and it's likely that many lawmakers, such as Issa and McCaul, are wealthier than their reports indicate.
