This was extremely unusual to watch.
The Fox anchor and debate moderator Chris Wallace had to tell the President to let his opponent speak.
Quote from the debate:
CHRIS WALLACE: The country would be better served if we allowed both people to speak with fewer interruptions. I'm appealing to you, sir, to do that.
Sir, you'll be happy. I'm about to pick up on one of your points.
PRESIDENT DONALD TRUMP: And we will protect...
WALLACE: President, I'm the moderator of this debate. And I would like you to let me ask my question.
Was the incumbent President afraid that his opponent would ask him questions that he would have to answer?
