Trump's debate mic appeared to cut off during health care answer

President Trump appeared to have his microphone cut off for a brief moment while he was explaining his health care plan during the final presidential debate in Nashville, Tenn., on Thursday night.

"We have done an incredible job on health care and we're gonna do even better ... " Trump said before his mouth continued to move but his voice was no longer heard.

NBC News correspondent Kristen Welker, the debate moderator, then directed the next question to Democratic nominee Joe Biden, following a short pause.

After the first Trump-Biden debate in Cleveland on Sept. 29 was plagued by interruptions and insults -- the majority by the president -- the Commission on Presidential Debates announced a change to the scheduled format.

Each candidate was afforded two uninterrupted minutes to speak at the beginning of each 15-minute topic, with the microphone cut for the candidate who is not speaking during that time.
