'If Mike doesn't come through, I won't like him as much'

US President Donald Trump has said at a rally in Georgia that he "won't like" his Vice-President Mike Pence if he doesn't "come through" when Congress meets to certify Joe Biden's White House victory.

As president of the Senate, Mr Pence will have the largely ceremonial responsibility of overseeing the session on 6 January and declaring Mr Biden winner.
