White House Press Secretary Jay Carney denounced the House report on the Benghazi terrorist attack as a a partisan Republican staff report,” adding that it falsely suggested then-Secretary Hillary Clinton gave false testimony to Congress earlier this year.

“The signature thing is a perfect example of an attempt to politicize something,” Carney told reporters when asked about the report, which noted that Clinton’s signature appeared on an April 2012 diplomatic cable denying a request for additional security at the U.S. mission in Benghazi. The House report said that the existence of the cable “contradicts” Clinton’s congressional testimony.

“It is standard protocol that cables originating in Washington go out under the authority of the current secretary,” Carney also said, explaining that Clinton’s signature would appear on that cable even though she never saw it.

Clinton told Congress in January that she was not aware of the requests for additional security. “The specific security requests pertaining to Benghazi, you know were handled by the security professionals in the department,” Clinton said. “I didn’t see those requests, they didn’t come to me, I didn’t approve them, I didn’t deny them.”
