The Pentagon estimated that 26,000 members of the military were sexually assaulted in unreported incidents last year — 35% more than in 2010 — a severe trend that senior officials warned could threaten recruiting and retention of women in uniform.

President Obama, reacting to the startling figures Tuesday, said he had "no tolerance" for sexual crimes in the ranks and pledged to crack down on commanders who ignored the problem. Obama said he had spoken to Defense Secretary Chuck Hagel and ordered that officers "up and down the food chain" get the message.
