Rep. Paul Broun (R-GA) laughs at Town Hall Meeting when asked: Who's Gonna Shoot Obama?"

A witness tells TPM that Rep. Paul Broun (R-GA) laughed when a man in a red shirt at his town hall meeting this week asked "Who's ...

Mark Farmer of Winterville, Georgia went to the meeting on Tuesday to ask a question about Social Security reform, and said in an e-mail to TPM he was "shocked by the first question and disgusted by the audience response."

"I was gravely disappointed in the response of a U.S. Congressman who also laughed and then made no effort to correct the questioner on what constitutes proper behavior or to in any way distance himself from such hate filled language," Farmer wrote.

After laughing at the question, Broun said "there's a lot of frustration with this president."

"We're going to have an election next year," Broun said. "Hopefully, we'll elect somebody that's going to be a conservative, limited-government president that will take a smaller... who will sign a bill to repeal and replace Obamacare."

Meanwhile, Broun hosted another town hall meeting last night, where he was cheered for cutting off funding to NPR and PBS as well as Planned Parenthood and said illegal immigrants need to be treated as criminals.

The voicemail box at Broun's Washington office was full on Friday morning.
