U.S. Sen. Richard Burr is the hardiest partier in Congress, according to a watchdog group that tracks fund-raising events.
The Sunlight Foundation's Party Time blog has 35 fundraiser entries for Burr in its database, more than any other member of Congress.
Fundraising events and receptions are not routinely disclosed to the news media, and the Party Time blog's work is not a complete list of all events.
Burr's events since June 2008 include golf outings and receptions at restaurants. They include events at private homes and one "Cigars and Cocktails" event that was hosted by Rudy Giuliani.
Burr, a Republican, is up for re-election next year.
In 2009, Party Time collected invitations for 3,660 parties and fundraisers for members of Congress.
