AARON GLANTZ:

It was stories like Dresen's that led to the president's executive order. The military followed up with new rules that ban inducements, including entertainment, for the purpose of securing enrollments of service members.

But what constitutes recruiting? The university paid for the reality TV star Big Smo to entertain the troops.

Here at Fort Campbell, the University of Phoenix is spending thousands of dollars to sponsor this concert. It's one of dozens of events the for-profit school is sponsoring on military bases across the country. The University of Phoenix's representative was introduced on stage as a friend of the military.

He gave away electronic devices. Fifteen minutes after the concert began, the Army kicked me off the base. An Army press officer told me off camera that I was asked to leave because I was talking on camera about the military's relationship with the University of Phoenix.

Robert Muth is a former officer in the Marine Corps. He runs a legal clinic for veterans at the University of San Diego.

ROBERT MUTH, University of San Diego: It looks like you have a corporate entity buying access to look like the preferred or the selected educational provider for the veterans or soon-to-be veterans at a base.
