The Republican just announced in committee his intention to vote NO on Bolton or at least his inability to vote yes at this time, pending new information. If a vote is pressed, this would tie up the committee. He absolutely shocked the Republicans and Democrats in the room. Holy cow. True surprises happen so rarely in these things that this one was worth hearing (some people play music at work, some people play C-Span audio...). Wow. It doesn't kill the nomination, but it would keep it in committee until somebody changes their mind. Shocking. and good.
Laura Rozen has some quotes and play-by-play at War and Piece.
Steve Clemons at The Washington Note has also been all over this story and promises to stay there.
