US president Joe Biden quipped that he got “sandbagged” after he tripped and fell – but was uninjured – while onstage at the US air force academy graduation.
Mr Biden had been greeting the graduates in Colorado Springs, Colorado, at the front of the stage with salutes and handshakes, and turned to jog back towards his seat when he fell.
He was helped up by an air force officer as well as two members of his US Secret Service detail.
Onlookers, including some members of the official delegation onstage, watched in concern before Mr Biden, who at the age of 80 is the oldest president in US history, returned to his seat to view the end of the ceremony.
“I got sandbagged,” the president told reporters with a smile when he arrived back at the White House on Thursday evening before pretending to jog into the residence.
Two small black sandbags had been onstage supporting the teleprompter used by Mr Biden and other speakers at the graduation.
“He’s fine,” White House communications director Ben LaBolt tweeted after the incident.
“There was a sandbag on stage while he was shaking hands.”
Mr Biden has been dogged by questions about his age and his fitness to serve, and his missteps have become fodder for political rivals as he campaigns for a second term in 2024.
He has stumbled before going up the stairs and on to Air Force One and he once got caught up in his bike pedals while stopping to talk to reporters near his home in Rehoboth Beach, Delaware.
Mr Biden’s personal doctor said after the president’s most recent physical examination in February that Mr Biden “remains a healthy, vigorous 80-year-old male, who is fit to successfully execute the duties of the presidency”.
Dr Kevin O’Connor also documented the president’s stiffened gait, which Dr O’Connor said was the result of spinal arthritis, a previously broken foot and neuropathy in Mr Biden’s feet.
Mr Biden is far from the first national political figure to stumble in public.
President Gerald Ford fell down while walking off Air Force One in 1975.
Republican senator Bob Dole of Kansas, the party’s presidential nominee at the time, fell off the stage at a campaign rally in 1996.
President Barack Obama tripped walking up the stairs to a stage at a 2012 event.
“I was so fired up, I missed a stair,” he told the crowd.
President Donald Trump’s gingerly walk down a ramp at the 2020 West Point commencement also sparked concerns about his health.
Mr Trump, 76, was campaigning in Iowa when he heard about Mr Biden’s stumble and alluded to his own episode.
“He actually fell down? Well I hope he wasn’t hurt,” Mr Trump said after an audience member told him about what had happened to Mr Biden.
“The whole thing is crazy. You gotta be careful about that … ’cause you don’t want that, even if you have to tiptoe down a ramp.”
The audience laughed as Mr Trump recounted slowly inching his way down what he said had been a slippery ramp at the US Military Academy graduation.
“If he fell, it’s too bad,” the former president said.
“We gotta just get this thing back on track. That’s a bad place to fall when you’re making, I think it was the Air Force Academy, right? That’s not inspiring.”
Meanwhile, Republican presidential candidate and Florida governor Ron DeSantis used the opportunity to take a political shot at Mr Biden while at a campaign event in New Hampshire.
“We hope and wish Joe Biden a swift recovery from any injuries he may have sustained,” he said, “but we also wish the United States of America a swift recovery from the injuries it has sustained because of Joe Biden and his policies.”
