President Obama and President-elect Donald Trump discussed the logistics of assuming responsibility for the sprawling operations of the administration during an “excellent” meeting Thursday, White House spokesman Josh Earnest said, but “didn’t try to resolve all their differences.”

“There was no staff in the room when President Obama and President-elect Trump sat down in the Oval Office for 90 minutes,” Earnest told reporters on Thursday. “I feel confident in telling you that they did not resolve all their differences.”
