The Post analyzed the financial disclosure forms and public records for all Congressional members from 2004 to 2010. Some key findings of the report are:
•By 2010, the median estimated wealth for members of the House of Representatives was $746,000; for senators it was $2.6 million.
•There was virtually no difference between the wealth of Republicans and Democrats in 2010. Just six years earlier, the net worth of Republicans was 44% higher than the net worth of Democrats.
•28% of Congress, or 150 members, reported earning more income from outside jobs and investments than from their Congressional salary of $174,000.
•27% of Congressional members saw a decline in their net worth between 2004 and 2010.
Lawmakers acquired their wealth in a variety of ways but real estate, institutional funds and the wealth of their spouses were the top three sources.
House Minority Leader Nancy Pelosi increased her wealth by an estimated $60 million between 2004 and 2010. The gains primarily came from the commercial real estate holdings of her husband, according to The Post. Representative Darrell Issa made his reported $448 million in commercial real estate as well as other financial investments.
