Rep. Darrell Issa (R-Calif.), Rep. Michael McCaul (R-Tex.) and Sen. Mark Warner (D-Va.) are the three wealthiest members of Congress, according to a new report by The Hill newspaper.

Issa, who earned his fortune in the car alarm business, has a minimum net worth of $355 million, according to The Hill. He takes over the top spot from McCaul, whose wife comes from the family that runs Clear Channel Communications and has a net worth of at least $101 million.

Both serve as chairmen in the House -- Issa of the Oversight and Government Reform Committee and McCaul of the Homeland Security Committee.

Warner, who some see as a potential presidential candidate or vice presidential pick in 2016, came in third with a net worth of at least $88.5 million.

Secretary of State John F. Kerry once topped the list of the wealthiest members of Congress but left the Senate earlier this year for his current job. Former senators Herb Kohl (D-Wis.) and Frank Lautenberg (D-N.J.) also were among the wealthiest lawmakers before departing the Senate. Kohl retired after the 2012 election, while Lautenberg died earlier this year.

As for potential 2016 presidential candidates, some of them rank among Congress's least wealthy members, including Sens. Marco Rubio (R-Fla.) and Kirsten Gillibrand (D-N.Y.).

Here's the recap from The Hill's Kevin Bogardus and Megan R. Wilson:

Rep. Paul Ryan (R-Wis.), the GOP's vice presidential candidate in 2012, reported a minimum net worth of $2.3 million, while conservative star Sen. Ted Cruz (R-Texas) posted wealth of $1.5 million.

Two other rising GOP stars, Sens. Rand Paul (Ky.) and Marco Rubio (Fla.), reported more modest financial means. While Paul's wealth stood at about $455,000, Rubio was in the red with a negative net worth of roughly $190,000.

On the Democratic side, Sen. Mark Warner (Va.) stood out among possible 2016 hopefuls with a minimum net worth of $88.5 million, good enough for third place on The Hill's list.

Two other Democrats in the 2016 discussion, Sens. Elizabeth Warren (Mass.) and Kirsten Gillibrand (N.Y.), fell on opposite ends of the financial spectrum. While Warren reported a portfolio worth at least $3.9 million, Gillibrand was barely in the black with a net worth of $166,000.
