HELENA, Mont. -

The U.S. Army formally reprimanded Democratic Senate candidate John Walsh in 2010 for using his position as Montana Adjutant General to solicit National Guard troops to join a private association.
Army Vice Chief of Staff Peter Chiarelli writes that Walsh's actions caused him to question Walsh's ability to lead.
Walsh's campaign said Tuesday he was not available for comment. He previously said he did not personally benefit and was seeking to help the Guard.
The reprimand came after an Army investigation into a complaint by a Montana National Guard officer that Walsh used his position to pressure subordinates to join the National Guard Association of the United States.
Walsh was seeking nomination to be the group's vice chairman.
Montana Television Network first reported the reprimand.
