US President Joe Biden fell on stage at the graduation ceremony of the US Air Force Academy in Colorado on Thursday, June 1.

It is reported by the publication ABC News.

According to reporters traveling with the president, Biden tripped over a black sandbag and pointed at it as he got up.

"He's fine. There was a sandbag on stage when he shook hands," Ben Labolt, the White House communications director, tweeted as video of the incident circulated online.

Biden, who delivered his opening speech and continued his handshake with graduates, fell at the podium and was quickly helped to his feet.

After an unfortunate embarrassment, 80-year-old Biden moved on unassisted and continued to stand and greet people until the end of the ceremony.

In his speech to graduates of the Air Force Academy, the President of the United States stressed that he, as commander-in-chief, has the honor to be here when military pilots take on the responsibility to serve and protect the country.

"In the coming years, you will be required to do even more. You will take on greater responsibility, and you will face a challenge that surpasses anything you have felt so far," the American leader said.

Earlier, on February 22 this year, President Biden tripped and fell on the stairs while boarding a plane at Warsaw airport.
