At least 268 of the 534 current Hill lawmakers had a net worth of more than $1 million in 2012, according to a Center for Responsive Politics examination of financial disclosures.

In addition, the median net worth of congressional members topped $1 million, up from $966,000 last year.

Democrats had a slightly higher net worth than Republicans: The median of Hill Democrats was $1.04 million, while Republicans’ median net worth was approximately $1 million.

Senators also had a higher net worth than members of the House with a median of $2.7 million, compared with $896,000 in the House. The party split was reversed in the Senate as Democratic senators reported a median net worth of $1.7 million versus $2.9 million for senators.

Rep. Darrell Issa (R-Calif.), a businessman in the car alarm industry, retook the mantle of wealthiest member of Congress with a net worth of $464 million in 2012. The title was held the year earlier by Rep. Mike McCaul (R-Texas), but his net worth tumbled from $500.6 million to $143.1 million in 2012, largely due to changes in reporting rules.
