The chairman of the Senate Armed Services Committee said Wednesday that it was premature for Navy Secretary Ray Mabus to say he would open all combat jobs to women before Congress had the opportunity to hold hearings and evaluate a recent Marine Corps study. Mabus drew criticism from lawmakers and Marines for saying that he would not ask for any Navy or Marine billets to remain male only, despite a Marine Corps study that found women performed worse than men in several different aspects of combat during a nine-month evaluation. "Why would you have a study if you're going to disregard the results of it?" Sen. John McCain, R-Ariz., told the Washington Examiner. While the official recommendation on whether to keep combat jobs closed to women will come from service secretaries, Pentagon press secretary Peter Cook said the defense secretary will also hear input from the Joint Chiefs, giving the Marine Corps commandant a chance to express his opinion on keeping jobs such as infantry open to only men.
