At a Rose Garden press conference yesterday, Trump said: "I am disappointed in the Attorney General. He should not have recused himself [from the Russia probe] almost immediately after he took office. And if he was going to recuse himself, he should have told me prior to taking office, and I would have, quite simply, picked somebody else. So I think that's a bad thing not for the President, but for the presidency. I think it's unfair to the presidency. And that's the way I feel."

Be smart: In this showdown, there's the potential for grave collateral damage to Trump. Many establishment/pragmatic Republicans, including lawmakers and administration officials and aides, "got there" on Trump not because they were wild about the man, but out of respect for the office (and self-interest, of course).

But one Hill alumnus told me that with his torture of Sessions, Trump seems to be demanding personal loyalty: "He's saying, 'I don't want the loyal Republican. I want the loyal Trumpite.'" That could trigger a disconnect that, in yet another echo of Nixon, would undermine the president's Washington support.

N.Y. Times Quote of the Day ... Mark Krikorian, executive director of the Center for Immigration Studies and a supporter of stricter immigration policies like those championed by Sessions: "If an early supporter like this is thrown under the bus, then who is safe? You can imagine what the other Cabinet secretaries are thinking."
