Breaking: Sen. Arlen Specter's first interview since crossing the aisle to the Democratic party will be on NBC's Meet the Press.

TVNewser has learned David Gregory will interview Specter live on Sunday.

> Update: Well MTP may be first, but not by much. Specter will appear on CBS' Face the Nation as well on Sunday. And a tipster writes: "Senator Specter's first interview is not Meet the Press — he was on air this morning with Michael Smerconish — just moments before he went to meet the President and Vice President. 7:15am this morning — that's the first interivew!!" Okay, so first TV interview...
