Rep. Barney Frank (D-Mass.) lit into Rep. Marsha Blackburn (R-Tenn.) on Sunday, when both appeared on ABC's "This Week."

The show started off civilly, with Frank responding to host George Stephanopoulos' questions about the political implications of President Barack Obama's endorsement of gay marriage. But when Blackburn answered the same questions by pivoting to a Republican talking point about women losing jobs under Obama, Frank responded with derision.

"This is a good political science lesson for people on what political parties' talking points are," Frank said. "My colleague Ms. Blackburn has been instructed to talk about the economics first, and while I would prefer to answer your questions, I do have to note that this Republican talking point that women have lost jobs -- the job losses came about because of the terrible recession that nonregulation in the economy brought about under George Bush."
