Joe Biden has proposed two televised US presidential election debates, which rival Donald Trump quickly accepted.

The first is proposed for June 27 and the second is set for a day to be announced in September.

The pair traded barbs on social media, with Trump stating: “Just tell me when. Let’s get ready to rumble!!!”

Biden said his opponent was free on Wednesdays – a reference to Trump’s criminal trial, while Trump claimed his rival was the worst debater who can’t put two sentences together.

But the President’s proposals break several traditions established over decades of presidential campaign.

The debates would bypass the presidential debate commission, which since 1988 has scheduled the timing of these election-year faceoffs and had already set dates and locations for three debates in the autumn.

According to US media, Biden’s team wants two televised debates to be conducted with no live audience – another break with tradition.

Candidates would take turns answering question from an agreed-upon moderator from a major news network and the non-speaking candidate’s microphone would be deactivated.
