President Joe Biden stumbled once again while ascending a short flight of stars at an event in Philadelphia Friday.

The president appeared to lose his balance while surmounting a trio of metal stairs with a railing just as he was walking to get onstage for his event.

He quickly caught his balance and made it up the stairs, which had a railing, and continued on with his event. 

The event, about ‘Bidenomics’ and investing in the U.S., is meant to tout $7 billion in investment in new Hydrogen production hubs. 

Biden, 80, has suffered a series of stumbles at events, including while de-boarding Air Force One, and falling to the ground after tripping on a sand bag at the Coast Guard Academy graduation this spring.

President Joe Biden climbs stairs to deliver remarks on his economic objectives at the Tioga Marine Terminal in Philadelphia, Pennsylvania, U.S., October 13, 2023. He briefly stumbled before regaining his balance and starting his event.

The stumble came before an event where Biden addressed a deeply serious topic: the American hostages detained inside Gaza.

He had spoken to family members of those held captive earlier Friday.

He also spoke about the ‘horrifying’ Hamas attack in Israel. He said of the militants who killed Israelis including women and children, ‘These guys make Al Qaeda look pure. They’re pure evil,’ he said.

It came on a brightly lit day where Biden wants to try to focus on his plans to grow the economy in jobs, even during a week where he has been contending with the Hamas attack on Israel and fears of a widening conflict

In late September, Biden slipped and almost fell while coming down the stairs of Air Force One. 

That happened while meeting with striking United Auto Workers in Michigan. 

It was another close call for the president, 80, who has taken several stumbles in his nearly three years in office – falling while boarding Air Force One, tripping on various staircases, and taking a dramatic tumble at the Air Force Academy when he encountered a sandbag.

The president is battling public concerns about his age and performance in opinion surveys. He has been continuing to try to campaign around the country while also holding official events outside DC, with polls showing him a in a close potential race with former President Donald Trump.

This week he filed paperwork to run in the Nevada Democratic primary, set for February. The filing deadline is October 16.

His top polling primary challenger, Robert F. Kennedy Jr., on Monday announced he would run as independent.
