When Donald Trump and Joe Biden face off on Thursday for a final televised debate, each candidate will have their microphones cut off while the other is delivering responses to questions.

The Trump campaign voiced objections to the change but said the Republican would still take part in the Thursday night event, one of his last chances to reach a large prime-time audience before voting ends on 3 November.

“President Trump is committed to debating Joe Biden regardless of last-minute rule changes from the biased commission in their latest attempt to provide advantage to their favored candidate,” campaign manager Bill Stepien said

Talking to reporters, Trump said the conditions of the debate were unfair: “I will participate but it’s very unfair that they changed the topics and it’s very unfair that again we have an anchor who’s totally biased.”
