Obama: It was "not my preference" to campaign for Biden

But, if he had his way, Obama says he would have preferred not to have been campaigning. During an interview with CBS News’ Gail King that aired on Sunday, Obama said, “It was not my preference to be out there.”

He explained, “I think we were in a circumstance in this election in which certain norms, certain institutional values that are so extraordinarily important had been breached, that it was important for me as somebody who had served in that office to simply let people know this is not normal.”
