Top two Air Force officials resigning
NBC: Secretary refused to fire chief of staff so both are forced out

WASHINGTON - The nation's top two Air Force officials are resigning, and military sources told NBC News Thursday that they were being forced out.

At the White House, press secretary Dana Perino said President Bush knew about the resignations of Air Force Chief of Staff Michael Moseley and Air Force Secretary Michael Wynne, but that the White House “has not played any role” in the shake-up.

Moseley, a general, is the Air Force's top uniformed officer. Wynne is the top civilian official.

Defense Secretary Robert Gates last week told Wynne to fire Moseley but Wynne refused, sources told NBC. As a result, Gates took the unprecedented step of asking both men to resign.
