McCain disses Lieberman?

Michelle Malkin caught John McCain refusing to come to Joe Lieberman's defense during a press conference. I wouldn't call it "under the bus," but it is certainly odd.

The way to handle a question like that is to say, "Hey, Joe can speak for himself. I'm proud to have his support, but I don't tell him what he can or cannot say, or put words in his mouth. If you've got a problem with something Joe said, take it up with him."
