More than one-third of the freshman lawmakers in the 112th Congress are millionaires, and as many as 15 are likely to rank among the richest Members of Congress this year, according to a Roll Call analysis of financial disclosure records.

Individual wealth varies widely among the new House and Senate lawmakers, from a handful who report deficits of up to several hundred thousand dollars to Sen. Richard Blumenthal (D-Conn.), who tops the list with a minimum net worth of about $64 million.

At least 40 freshmen reported a minimum net worth of $1 million or more. Among those lawmakers, at least 15 have a minimum net worth of $5 million or more, likely placing them among the 50 richest Members of Congress.

Roll Call’s survey includes 112 freshman lawmakers, including the five Members elected in November but sworn in to their respective chambers during the 111th Congress.

Among the 15 wealthiest members of the freshman class, four are Senators and 11 are House lawmakers. Blumenthal is the only Democrat.
