Three Republican senators who met Tuesday with U.N. Ambassador Susan Rice say they are more troubled now over her initial explanations about the deadly Sept. 11 raid in Libya.

Rice, however,  insists there was "no intention to mislead the American people" on the events at the U.S. consulate in Benghazi, Libya, where an attack in September killed four Americans.

In a statement, the U.N. ambassador says the "talking points provided by the intelligence community" had been wrong.

Rice met behind closed doors today with Sens. John McCain, Lindsey Graham and Kelly Ayotte — three of her harshest critics. And afterward, they said they're more troubled than ever with Rice's comments in the days after the attack, in which she said it was the result of a protest, and not terrorism.

The lawmakers said the Obama administration still must answer questions about the attack.

The controversy could stand in the way of Rice's expected nomination to be secretary of state.

Ayotte said Rice told them that her national television description that a spontaneous demonstration triggered the attack on the U.S. consulate was wrong. She had made the comments five days after the raid based on intelligence information.

Obama is considering Rice as a successor to Secretary of State Hillary Rodham Clinton.
