Steady on, Joe! Biden almost slips on the stairs to Air Force One, AGAIN, amid increasing concerns about the 79-year-old's health and mental state

Joe Biden nearly fell up the stairs of Air Force One, again, on Wednesday amid concerns about his health and mental state.

The president was on his way to Illinois to discuss the recent downtick in - but still at a 40-year high - inflation, when he slipped as he entered Air Force One. 

The gaffe was reminiscent of last year's tumble where the Biden fell three times while trying to board the plane in Atlanta, with the White House blaming strong gusts of winds for the president's falls.

There were no injuries reported as the president made his way to Illinois for a speech.

Biden, 79, who became oldest American to be inaugurated as president at 78, has garnered concerns over his health as his presidency has been marred with blunders and slips of the tongue. 

Concerns about the presidents age were brought up throughout his campaign against Donald Trump, and shortly after his election win in November 2020, Biden suffered a broken foot while playing with his dog, Major.

In November 2021, Biden underwent a colonoscopy and briefly transferred power to Vice President Kamala Harris, making her for a time the first acting female President in US History. Biden took control back after the procedure.

During the operation Mr. Biden had a small polyp on his colon removed which was later found to be benign. His 2019 medical examination found that he took medication for several common age-related conditions like elevated cholesterol and a minor heart arrhythmia. 

Concerns over his health resurfaced in March 2021, when the president was filmed tumbling three times on his way to board Air Force One. 

Last month, Biden led a speech regarding the supply chain crunch at the North Carolina Agricultural and Technical State University, but the speech was undermined when he suddenly turned his back to the audience to shake hands with nobody. The president was likely expecting someone to appear beside him for the moment, but he remained alone on the stage, looking around, before wandering off stage.

He had also incorrectly stated that he had served as a 'full professor' at the University of Pennsylvania despite never teaching a class at the school.

In addition, Biden has had to contend with other slips of the tongue, like when he referred to his new granddaughter as his son, Beau, during his campaign.

Earlier this year, he also mistakenly referred to Vice President Kamala Harris as 'president' and had been pictured wandering aimlessly during Barack Obama's visit to the White House.

Republicans have cited Biden's alleged cognitive decline as the main reason for the current administration's backtracking over the president's other recent verbal blunders: first telling US troops in Warsaw, Poland, that they were about to go to Ukraine, before suggesting that the US might engage in using chemical weapons on Russia.
