WASHINGTON (AP) - Sexual assaults in the military are a growing epidemic across the services and thousands of victims are still unwilling to come forward despite a slew of new oversight and assistance programs, according to a new Pentagon report.
    
Troubling new numbers estimate that up to 26,000 military members may have been sexually assaulted last year, according to survey results released against a backdrops of scandals including an ongoing investigation into more than 30 Air Force instructors for assaults on trainees at a Texas base
    
The report was released Tuesday and comes just days after the Air Force's head of sexual assault prevention was arrested on charges of groping a woman in a Northern Virginia parking lot. And it follows a heated debate over whether commanders should be stripped of the authority to overturn military jury verdicts, such as one officer did in a recent sexual assault conviction.
    
In a sharp rebuke Tuesday, President Barack Obama said he has no tolerance for the problem and that he had talked to Defense Secretary Chuck Hagel about it. He said any military member found guilty of sexual assault should be held accountable, prosecuted and fired.
    
"I don't want just more speeches or awareness programs or training, or ultimately folks look the other way," the president said. "We're going to have to not just step up our game, we have to exponentially step up our game to go after this hard."
