Obama warns McCain: Go after U.N. Ambassador Rice? ‘You have a problem with me’

President Barack Obama bluntly told Sen. John McCain and other Republicans to lay off their attacks against U.N. Ambassador Susan Rice over the Benghazi assault, telling lawmakers that if they go after her "then you have a problem with me." And Obama, speaking at his first postelection press conference, vowed that Republican opposition would not dissuade him from nominating Rice to replace departing Secretary of State Hillary Clinton.

"I don't think there's any debate in this country that when you have four Americans killed that's a problem," he told reporters in the East Room of the White House. "And we've got to get to the bottom of it, and there needs to be accountability. We've got to bring those who carried it out to justice—they won't get any debate from me on that.

"But when they go after the U.N. ambassador, apparently because they think she's an easy target, then they've got a problem with me," he warned.
