Donald Trump has repeatedly criticized the presidential election as rigged and refused to commit to conceding if he loses the race.
As Election Day begins, some are asking what would happen if Trump loses and declines to concede.
The answer is: Nothing.
There is no legal or constitutional requirement that a losing candidate publicly concede, experts told NBC News.
A refusal to concede in the face of a clear loss would certainly be unusual — and probably controversial — but it would not impact the formal results in any way.
