President Barack Obama says Republican Mitt Romney "seems to have a tendency to shoot first and aim later."

Obama, in an interview with CBS News' "60 Minutes," said Romney "didn't have his facts right" when he criticized U.S. officials for their initial response to protests at the U.S. embassy in Egypt.

White House press secretary Jay Carney read Obama's answer on a flight to Las Vegas, where Obama is scheduled to gave a campaign speech.

Obama said that as president, he has learned it's important to — in his words — "make sure that the statements that you make are backed up by the facts."

Asked if Romney's remark were irresponsible, Obama said he would let the American people judge that.

WASHINGTON (AP) — President Barack Obama is condemning in the "strongest possible terms" an attack on the U.S. consulate in Libya that killed four Americans, including the American ambassador.

Obama on Wednesday said the U.S. will work with the Libyan government to bring the perpetrators of the attack to justice. He says "no acts of terror" will shake America's resolve.

Obama said the U.S. rejects any efforts to denigrate the religious beliefs of others, but says there is "absolutely no justification" for violent attacks.
