President Joe Biden and former President Donald Trump agreed on Wednesday to participate in two moderated debates in the months before the fall elections.

Jennifer Dillon, the campaign chair for Biden, informed the Commission on Presidential Debates that the commander-in-chief would not participate in the three events they had scheduled for this fall. The campaign instead proposed to the Trump team through a challenge video posted on social media that the candidates face one another on June 27 and September 10.

“Donald Trump lost two debates to me in 2020,” Biden said. “Since then, he hasn’t shown up for a debate. Now he’s acting like he wants to debate me again. Well, make my day, pal.”

Trump responded to the challenge on Truth Social, calling Biden the “worst debater” he has ever faced and contending that “he can’t put two sentences together.”

“I am ready and willing to debate Crooked Joe at the two proposed times in June and September,” he wrote. “I would strongly recommend more than two debates and, for excitement purposes, a very large venue, although Biden is supposedly afraid of crowds.”

The rules for the two debates include requirements that they are hosted in a television studio without a live audience. The Biden team also asked for microphones which mute themselves when time is expired, an apparent attempt to decrease improper interruptions.

The unorthodox debate arrangements, which marks a departure from nearly four decades of the Commission on Presidential Debates hosting the events, come as Democratic operatives also consider hosting the Democratic National Convention through a remote or hybrid format, which occurs as protesters denounce senior Democrats over their support for Israel over Palestine.
