The combined wealth of Congress is set to plummet next year after a deluge of departures and the results of the midterm elections. Some of the wealthiest lawmakers on Capitol Hill won’t be returning next year, and the body’s $2.43 billion of personal net worth will drop by $933 million.

Biggest retirements

Of the top 10 richest members of Congress, four are packing their bags. Most are staying in the public sector. California Rep. Darrell Issa, net worth of $283 million and the perennially richest member of Congress, announced his retirement in January 2018. The inventor of the Viper car alarm was expected to leave public office but will move to the Trump administration, after being appointed to the U.S. Trade and Development Agency.

Colorado Rep. Jared Polis won his gubernatorial bid and will be sworn in come January. A tech investor, Polis brings his net worth of $122 million to the state capital.

Rep. Dave Trott, whose seat flipped for Democrat Haley Stevens in 2018, returns to the private sector with $119 million.

Maryland’s John Delaney does not have an immediate home after 2019, but he’s set his sights on the White House. The third-term lawmaker and former private equity investment executive announced on July 2017 that he would make a run at the presidency.
