Air Force Academy to replace four leaders in sexual assault scandal

The Air Force officials also said two women would be included in the new leadership, the Associated Press reported.

Clinton spoke after Air Force Secretary James Roche and others gave a closed-door briefing to senators to discuss the allegations that female cadets at the academy were ostracized and reprimanded after they reported they were raped.

"No, I'm not satisfied, but I believe they are making progress," Clinton said. "I believe that changing the leadership is a serious action, but it is not sufficient."

A formal announcement was expected from the Air Force Wednesday, when changes in policies and procedures also were to be announced.

Three Republicans-Sens. Wayne Allard of Colorado and John Warner of Virginia and Rep. Tom Tancredo of Colorado-have all called for a change in leadership at the academy.
