In a statement, Dr Sean Conley, the president’s physician, says the couple “are both well at this time, and they plan to remain at home within the White House during their convalescence”.

Mr Trump is said to have “mild symptoms”.

Press secretary Kayleigh McEnany says Mr Trump is “fatigued but in good spirits” and is being evaluated by experts.
