"There is never a perfect time for this type of transition, but now is the right time," Ballmer said in a statement.

Trump said the lawsuit is false and politically motivated. Schneiderman said many of the 5,000 students who paid up to $35,000 thought they would at least meet Trump but instead all they got was their picture taken in front of a life-size picture of "The Apprentice" TV star. "Trump University engaged in deception at every stage of consumers' advancement through costly programs and caused real financial harm," Schneiderman said. "Trump University, with Donald Trump's knowledge and participation, relied on Trump's name recognition and celebrity status to take advantage of consumers who believed in the Trump brand." 7. -- Spain's Telefonica agreed to raise its bid for KPN's German unit E-Plus to a package worth $11.4 billion, and KPN's largest shareholder, America Movil, said it supported the deal.
