The Consumer Financial Protection Bureau’s Holly Petraeus goes on the attack, saying a federal rule encourages for-profit colleges to exploit veterans. Federal aid can make up no more than 90 percent of a for-profit college's revenue. But veterans' benefits don't count. In testimony before the Senate Homeland Security and Governmental Affairs Committee, Petraeus will say the rule gives "some for-profit colleges an incentive to see servicemembers as nothing more than dollar signs in uniform and to use some very unscrupulous marketing techniques.”
