UNITED NATIONS (AP) — U.S. Ambassador Susan Rice said Wednesday that her early account of the attack that killed the U.S. ambassador to Libya and three other Americans in Benghazi was based on the initial intelligence community assessments and was always subject to review and updates.

She said she respects Republican Sen. John McCain, who has been critical of her, but says "some of the statements he's made about me have been unfounded, but I look forward to having the opportunity at the appropriate time to discuss all of this with him."

Her comments attributing the attacks to a mob enraged over an anti-Muslim video posted on YouTube were widely denounced by Republicans during the U.S. presidential campaign. The attack came on the 11th anniversary of the Sept. 11, 2001 terror attacks on the United States, and her critics said it was clearly a terrorist attack aimed at the anniversary. U.S. Ambassador Chris Stevens and three other Americans were killed.

The focus has fallen on Rice because she is a longtime White House insider and is believed to be President Barack Obama's first choice to replace Secretary of State Hillary Clinton, who is not expected to stay on during his second term.
