WASHINGTON -- Minnesota's eight House members and both senators collectively urged the Army Tuesday to clarify a new directive expanding legal services to victims of sexual assault in the National Guard.

The Army recently released new rules expanding important legal services to certain victims of military sexual assault, but the rules don't cover National Guard members who become victims of sexual assault outside drill weekends or military duties.

Minnesota's ten members of Congress say the directive will undermine the Minnesota National Guard's ability to "effectively provide support services to survivors of sexual assaults," according to a release.

The letter was led by Democratic Sen. Amy Klobuchar and GOP Rep. John Kline and co-signed by Democrat Sen. Al Franken and Reps. Collin Peterson, Betty McCollum, Keith Ellison, Tim Walz and Rick Nolan, and Republican Reps. Michele Bachmann and Erik Paulsen.

"Our Minnesota service members should not be impeded from seeking critical services in the aftermath of a sexual assault," the letter said. "The Army must provide clear guidance and direction in order for the National Guard to effectively provide these services authorized by Congress."

The letter comes as the Department of Defense scrambles to deal with the increasing problem of sexual assaults in the military. According to the delegation release today, the DoD found in May that overall reporting of sexual assaults in the military in 2013 was 50 percent higher than it was the previous year -- 5,061 in 2013 versus 3,374 in 2012. Previous year-to-year increases in reporting never exceeded five percent.

There are more than 13,000 soldiers and airman in the Minnesota National Guard.
