There was no clear problem with his microphone during the debate.
The GOP nominee has often joked on the campaign trail about faulty microphones, saying on occasion that he may refuse to pay for the audio rental. He repeated that joke last week during a campaign event in Kenansville, N.C.
“The mic just shot. That was a weird sound, wasn't it? So I wouldn't pay the mic guy and they'll say, 'Isn't that terrible. He didn't pay his bills,' ” Trump said at the time. “When people don't do a good job for me I don't pay them. It's one of those things.”
Overall, however, he said he felt he did well against his Democratic rival, Hillary Clinton.
"I thought it was a very fair debate," Trump told reporters Tuesday night. "The polls are all saying we won."
