Ahead of final US Presidential debate, new rules allow to mute microphones

Ahead of the final US presidential debate, the non-partisan Commission on Presidential Debates has announced new rules under which it will mute microphones for two minutes of the rival speakers so as to give them uninterrupted opening remarks.

Incumbent Republican President Donald Trump, 74, and his Democratic challenger Joe Biden, 77, are slated to face their final debate at Belmont University in Nashville, Tennessee on October 22.

Under the new rules, Trump and Biden will each have two minutes of uninterrupted time to speak at the beginning of every 15-minute segment of the debate.

"The only candidate whose microphone will be open during these two-minute periods is the candidate who has the floor under the rules," the commission said in a statement on Monday.

"For the balance of each segment, which by design is intended to be dedicated to open discussion, both candidates' microphones will be open," it said.

The commission said both campaigns have agreed to the two-minute, uninterrupted rule.

The decision to mute microphones comes after a chaotic first presidential debate that saw significant interruptions from both major party candidates, primarily from Trump.

The September 29 debate, moderated by Fox News anchor Chris Wallace, was widely criticised for its off-the-rails nature.

The second presidential debate set for October 15 was cancelled after Trump refused to do a virtual face-off with his Democratic challenger despite concerns over his Covid-19 diagnosis. The presidential rivals separately held competing town halls last week instead.

The third and final debate will be moderated by NBC News correspondent Kristen Welker.

In a late Monday night statement, Trump 2020 campaign manager Bill Stepien said Trump is committed to debating Biden regardless of the last-minute rule changes.

"This was supposed to be the foreign policy debate, so the president still looks forward to forcing Biden to answer the number one relevant question of whether he's been compromised by the Communist Party of China,” he said.

Earlier in the day, Stepien in a letter to the commission expressed concern over the announced topics for what was always billed as the 'Foreign Policy Debate' in the series of events agreed to by both the Trump and the Biden campaigns many months ago.

"The topics announced by moderator Kristen Welker (fighting Covid-19, American families, race in America, climate change, national security, and leadership) are serious and worthy of discussion, but only a few of them even touch on foreign policy,” he said, asserting that almost all of the topics were discussed at length during the first debate "won" by Trump.

"As is the long-standing custom, and as had been promised by the Commission on Presidential Debates, we had expected that foreign policy would be the central focus of the October 22 debate. We urge you to recalibrate the topics and return to subjects which had already been confirmed,” Stepien said.

Stepien in his letter also opposed the move to mute the mics.

"It is completely unacceptable for anyone to wield such power, and a decision to proceed with that change amounts to turning further editorial control of the debate over to the Commission which has already demonstrated its partiality to Biden. This is reminiscent of the first debate in 2016, when the President's microphone was oscillated, and it is not acceptable," he said.
