Mayor of Philadelphia tells Trump to "put his big boy pants on" and accept defeat.

Philadelphia mayor, Democrat Jim Kenney said Donald Trump needs to “put his big boy pants on” and accept the results of the election so the country can move on.

“I think what the president needs to do is, frankly, put his big boy pants on. He needs to acknowledge the fact that he lost and he needs to congratulate the winner just as Jimmy Carter did, just as George H.W. Bush did and, frankly, just as Al Gore did and stop this and let us move forward as a country,” Kenney said during a Friday news conference.
