If Frist released this on his official stationary then I would say it is going to happen. While no big fan of Frist I don't believe it is reasonable to distrust him. I mean it isn't like he is Hillary Clinton though apparently many around here believe him to be.
It's not that i distrust him, just that we've heard similar things before...
Repeat: Frist's office just announced a "background briefing" for reporters in his office at 3:30 p.m. Check the wires at 4:30 or so to see the stories that come out with "sources close to Senator Frist" discussing the nuclear option.
