Hot Air has the details, but just more evidence that McCain is done as far as 2008 is concerned.

Account via the Washington Post blog:

“Sen. John McCain (R-Ariz.) hasn’t spent much time in the Capitol this year as he seeks the GOP presidential nomination. But one of his rare appearances this week provided a pretty salty exchange with a fellow Republican.

During a meeting Thursday on immigration legislation, McCain and Sen. John Cornyn (R-Texas) got into a shouting match when Cornyn started voicing concerns about the number of judicial appeals that illegal immigrants could receive, according to multiple sources — both Democrats and Republicans — who heard firsthand accounts of the exchange from lawmakers who were in the room.

At a bipartisan gathering in an ornate meeting room just off the Senate floor, McCain complained that Cornyn was raising petty objections to a compromise plan being worked out between Senate Republicans and Democrats and the White House. He used a curse word associated with chickens and accused Cornyn of raising the issue just to torpedo a deal.

Things got really heated when Cornyn accused McCain of being too busy campaigning for president to take part in the negotiations, which have gone on for months behind closed doors. “Wait a second here,” Cornyn said to McCain. “I’ve been sitting in here for all of these negotiations and you just parachute in here on the last day. You’re out of line.”

McCain, a former Navy pilot, then used language more accustomed to sailors (not to mention the current vice president, who made news a few years back after a verbal encounter with Sen. Patrick Leahy of Vermont).

“[Expletive] you! I know more about this than anyone else in the room,” shouted McCain at Cornyn.”

Yep, stick a fork in him, he’s done.
