Biden – the oldest president ever to take office – then returns to his private quarters, known as The Residence. Sources told CNN he retires earlier than Trump, who would often fire off tweets around midnight, or in the early hours of the morning.

Other past presidents – including Biden’s former boss Barack Obama – would also stay up late working on briefings and papers. Biden begins his mornings by having coffee with his wife Jill, and kicks off his meetings around 9am. His days are said to be far more ‘structured’ with meetings than Trump’s.

The former president would block off large portions of his working day for ‘executive time’, only to settle down in front of the TV or call his pals, it is claimed.

President Biden and his wife Jill are the first first couple not to live with their children at the White House since George HW Bush took office in 1988

And whereas Trump took a famously laissez-faire attitude to masks and social distancing in the White House, President Biden is said to be happy to video-conference with top officials who cannot meet him in person.

The Bidens are the first first couple since George HW and Barbara Bush not to have children living with them at the White House.

They are an affectionate couple, who enjoy spending time with each other, their children and grandchildren, people close to them say.

President Biden will hit another milestone on Friday when he makes his first trip aboard the presidential Boeing 747.

Any plane carrying the president receives the call-sign ‘Air Force One,’ but Tuesday’s flight to a town hall in Milwaukee, Wisconsin, will be Biden’s first trip as president on the plane most commonly associated with the nickname.
