“These are people who don't know what they're talking about,” she added.
Clinton was expected to testify about an independent review of security measures in Libya prior to the attack that killed Ambassador Christopher Stevens and three other Americans on Sept. 11. Her deputies will be going in Clinton's place but the secretary has told Congress she may testify next year.
“I think she was waiting for the report so she could find out what it said and then fashion her testimony accordingly,” Bolton said. “There is nothing more embarrassing than to say something and then have it contradicted and have to change your story later.”
Republicans have slammed President Obama and his State Department for security lapses in Libya following revelations that Stevens asked for more security and was turned down. The attack has already claimed one political scalp after Susan Rice, who has Bolton's old job at the U.N., abandoned her bid to replace Clinton as secretary of State in the face of intense Republican criticism. Republicans targeted Rice for initially linking the Benghazi attack to a peaceful protest gone awry.
