Biden stumbles climbing ‘windy’ steps to Air Force One

White House spokesperson says the US president is ‘doing fine’ after ‘misstep’, and he did not require medical attention.

US President Joe Biden stumbled on Friday climbing the stairs to board Air Force One for a flight to Atlanta. Biden took a jaunty 10 steps up the stairs before tripping, catching himself, taking a couple more steps and then tripping twice more. The president briefly gathered himself, smoothed his left pant leg over his knee and carried on deliberately to the top of the steps. He turned smartly and gave a quick salute to Air Force personnel on the runway.
