The only Republican in the House to vote for a Democrat-backed health care bill says he has had two fundraisers canceled since Saturday's vote, and some campaign contributors have asked for their money back. But Rep. Anh "Joseph" Cao said Tuesday he stands by the vote. "At the end of the day we all have to represent our respective districts," he said in an interview. (AP Photo/Bill Haber, File)
