From a press conference a little earlier:

Let me just conclude with an apology. I don’t see the
reporter that I jumped on yesterday, but I was asked one too many
times about Republican defections. I think it was after the third or
fourth time we had prevailed.
And looking at this week in review, as Senator Graham started
this little conference, it occurs to me that the story that I see
leading the headlines every day about Republican defections is not the
story at all.
The story is that after all of the bluff and bluster and after
all of the political machinations and the efforts to use the defense
authorization bill for the political purposes that have been described
here and the purpose of undermining the mission of our troops, at the
end of the week, we’re left where we were at the beginning — namely,
we support the president’s policy; we support General Petraeus’
mission and we support the efforts of our troops. And not a single
vote has undercut that mission or that support.
