239 millionaires in the House and Senate. But it still reflects the fact that the average lawmaker is far wealthier than his or her typical constituent. While about one percent of Americans are millionaires, 44 percent of those serving in Congress can claim as much.

"The biggest takeaway from all of this is that even thought the collective wealth of members of congress appears to have declined, members of Congress are still so much more wealthy than the average American – and even more wealthy than a lot of wealthy Americans," CRP spokesman Dave Levinthal told Hotsheet.

The richest member of Congress is Republican California Rep. Darrell Issa, whose net worth is estimated to be in excess of $250 million. He's followed by four Democrats: California's Jane Harman (approx. $245 million), Wisconsin's Herb Kohl (approx. $215 million), Virginia's Mark Warner (approx. $210 million) and Massachusetts' John Kerry (approx. $209 million).

Among the top 25 wealthiest legislators – which includes boldface names Nancy Pelosi, Dianne Feinstein and Olympia Snowe – there are 14 Democrats and 11 Republicans.
