Hagel did it.
At the time, I asked who could have done it, but that's only because I'm a doofus. I had already blogged the answer on the same day, and it wasn't until MadMustard (very funny by the way) pointed out Hagel's presidential ambitions that it all connected.
Let's quickly run through it. The Bush administration gave McCain the key to the party, the Bush's fundraisers list, reported on the 18th by Novak, but it certainly took place earlier. On the 17th, Hagel's local paper prints a scything quote by Hagel about the Cheney shooting that was certain to get national coverage, and then last night, he tells the WaPo everything he knows about the White House's efforts to cover their illegal spying.
Hagel is one pissed off Senator. Keep an on it, as he is the swing vote on the Intel committee, it could get really fun.
