The commission, which oversees US Presidential debates, says it will change the format to ensure the remaining 2 encounters between Donald Trump and Joe Biden are more orderly.
One new measure could be to cut the microphones if the candidates try to interrupt each other.
The announcement follows Tuesday’s ill-tempered debate, which descended, into squabbling, bickering and insults.
President Trump’s team has already criticised the commission’s plans.
The tone and tactics of the first Presidential debate were slammed across the US and around the world.
The Trump-Biden debate pulled in 65 million TV viewers.
