"Republican U.S. Sen. Kelly Ayotte is coming under fire from her opponent for accepting donations from Bridgepoint Education, which being investigated by the U.S. Department of Justice. Ayotte, who is facing Democratic Gov. Maggie Hassan in one of the country's most competitive Senate races, last month returned the $8,000 in donations from Bridgepoint after she learned of the company's problems. She received four donations over two years. Hassan's campaign has stepped up efforts this week to highlight the donations and suggested Ayotte tried to cover them up, something Ayotte has denied."
