House Budget Committee Chairman Paul Ryan (R-WI) blamed the liberal blog ThinkProgress and others for some of the rowdy town hall meetings he recently faced.

"My town halls were phenomenally, overwhelmingly supportive," the congressman told Bloomberg. "And this was after – you know, it was reported by the media that MoveOn, ThinkProgress, the labor council from Milwaukee were doing training sessions and trying to stack the crowds."

An audience at a town hall in Milton, Wisconsin booed Ryan in April when he tried to defend his proposal to extend tax breaks for the wealthiest Americans.

ThinkProgress denied the allegation that it stacked the crowds at town hall meetings.

"We didn’t bus people in, tell anyone to attend, or in any other way coordinate with Wisconsinites to oppose Ryan’s reforms," Igor Volsky of ThinkProgress explained. "While it is true Ryan did find overwhelming support at most of his meetings — receiving at least two standing ovations and several requests that he run for president — the Congressman was also routinely challenged by his constituents on his plan to lower tax cuts for the rich."

Ryan told ABC's Christiane Amanpour that the outraged constituents he and other Republican congressmen recently faced at town hall meetings was "a sign of misinformation perpetrated out there."
