The allegations of abuse come soon after an Air Force officer was charged with sexual battery stemming from an incident in Northern Virginia.
Lt. Col. Jeffrey Krusinski, a 1994 graduate of the Air Force Academy who served tours in both Iraq and Afghanistan, was arrested this month and accused of grabbing a woman's buttocks and breasts in a parking lot in Arlington County not far from the Pentagon.
He had been in charge of a military unit aimed at preventing sexual assault.
Krusinski, who has since been removed from that position, made an initial court appearance last week. He did not enter a plea.
"To say this report is disturbing would be a gross understatement. For the second time in a week, we are seeing someone who is supposed to be preventing sexual assault being investigated for committing that very act," said U.S. Sen. Kirsten Gillibrand, D-New York.
She plans to unveil legislation this week that would remove chain of command influence from the prosecution of such offenses.
"We have the best and the brightest serving in our military. We have the greatest military in the world. And we ask everything of them. We ask them to even die for their country. We should not be allowing them to be subject to sexual assault and rape," said Gillibrand.
