The third and final Presidential Debate between US President Donald Trump and Democratic nominee Joe Biden will see organisers hit the mute button at the top of each topic.
Each candidate will have two minutes of uninterrupted time at the beginning of each 15-minute segment of the debate, with the opposing candidate’s microphone muted.
After each has had their two minutes, open discussion will be allowed and both candidates’ microphones will be on.
Moderator Kristen Welker will not have control of a mute button and will be able to return any time taken up by interruptions back to a candidate.
The Commission on Presidential Debates noted both campaigns had agreed to debate rules.
“We realise, after discussions with both campaigns, that neither campaign may be totally satisfied with the measures announced today,” it said.
“We are comfortable that these actions strike the right balance and that they are in the interest of the American people, for whom these debates are held.”
All 5 Australian networks will screen the Debate Live to Air at 12pm AEDT on Friday.
