Trump, the presumptive Republican nominee, has goaded Biden about debating – despite skipping all debates in his own primary this year; withdrawing from his second debate with Biden in 2020; and in 2022 prompting the Republican National Committee to withdraw from the body that organises presidential debates.

Trump’s last White House chief of staff, Mark Meadows, also revealed that when Trump and Biden did meet on the debate stage, in September 2020, Trump had tested positive for Covid-19 but declined to tell the public.

Trump and members of his family then flouted Covid protocols around the debate with Biden.

The interview between Biden and Stern was announced minutes before the conversation began on air.

Reporting the unscheduled stop in New York, the White House pool report said.

“At 10.05am, the motorcade made an unscheduled stop at Sirius XM studio in midtown Manhattan.”

Jennifer Witz, chief executive of Sirius XM, said: “We are thrilled that President Biden chose Howard Stern.

It’s just another reminder that Howard is in a league of his own, regularly lauded as the world’s best interviewer.”

That would be up for debate but Stern does have a habit of making news – often, in the case of Biden’s White House predecessor, retrospectively.

Trump’s interviews with Stern before entering politics have regularly resurfaced, particularly over Trump’s usually controversial, often lewd and sometimes disturbing remarks.
