Chris Matthews vs. Reince Priebus on MSNBC's 'Morning Joe'

On Monday's Morning Joe, MSNBC host Chris Matthews and RNC chair Reince Priebus entered into an incredibly tense argument that kicked off with Matthews disagreeing with Priebus' comments about the Democrats running a more negative campaign that Republicans, pointing in particular to Mitt Romney's recent joke referencing birther concerns over Barack Obama's birth certificate. "It is an embarrassment to your party to play that card," said Matthews, accusing Republicans of playing the race card with both that comment and claims that Obama had made changes to welfare work requirements.

Matthews grew increasingly angered during the discussion, particularly when Priebus began mentioning "foreign influences" on Obama's policies as the show's hosts attempted to moderate the discussion. "I'm not going to get into a shouting match with Chris, so," said Priebus, later calling his accusations "garbage." Edit: I had initially misheard Matthews' response to the chairman's comment as "You're garbage." In fact, Matthews replied "it's your garbage." Apologies for the mistake, and thanks to those who pointed it out. Have a look, courtesy of MSNBC:
