Mr Biden, who beat Republican Mr Trump in November’s election, is due to receive his first presidential daily briefing on Monday. This was made possible by the announcement a week ago that the transition process had begun.
Mr Biden, who turned 78 earlier this month, will become the oldest US president to take office after he’s inaugurated on 20 January next year.
Given this, Mr Biden’s health is expected to be watched closely by allies and opponents.
His doctor described him as “healthy, vigorous” and “fit to successfully execute the duties of the presidency” in a medical report released last December.
Mr Biden is set to bring his two German shepherds – Champ and Major – with him to the White House.
The president-elect and his wife, Jill Biden, fostered Major from a dog shelter in Delaware and made his adoption official in November 2018.
Champ lived with the Bidens on Capitol Hill in Washington DC during Barack Obama’s presidency, when the former senator for Delaware was vice-president.
