U.S. Sen. John McCain is calling for establishment of a Watergate-style congressional committee to investigate the deaths of four Americans, including Ambassador Christopher Stevens, at the U.S. Consulate in Benghazi, Libya.

The Republican tells CBS he believes the unanswered questions surrounding the events on Sept. 11 require such a select committee.

McCain accused the Obama administration of making misleading statements. He also said U.N. Ambassador Susan Rice went on national television and said incorrectly that the violence was the result of a demonstration against an anti-Muslim movie made in the United States. Asked if he'd stand in the way of any nomination of Rice as the next secretary of state, McCain replied, "She's not qualified."

He said Rice spoke "in defiance" of the facts in the case.
