Specter Interrupts Sestak at Progressive Forum

(TPM) - At a Pennsylvania Progressive forum this Saturday, Sen. Arlen Specter (D-PA) and Rep. Joe Sestak (D-PA) were supposed to be doing separate Q&As, one after the other. But Specter apparently jumped the gun and climbed onstage while Sestak was giving his closing remarks, and a moderator asked him to get off the stage.
