Yet more questions were raised about President Joe Biden's fitness last week after a viral video recording showed him stumbling on the steps of Air Force Once.

The problem is said to have gotten so bad that a Secret Service agent is assigned to stand at the bottom of the stairs whenever he gets on or off the plane. 

Biden has begun using a shorter staircase

That's according to a New York Times article published earlier this month, which also noted that the president has "started taking a short flight of stairs directly into the belly of Air Force One, rather than a tall stairway wheeled up to a higher point on the plane."

The change was made in response to an incident last year in which Biden tripped while handing out diplomas to graduates of the Air Force Academy.

Biden's problems with getting around aren't just limited to air travel, however, as former President Donald Trump recently mocked the confusion he often exhibits following public events.

"He makes a speech that lasts usually about a minute and a half because the octane starts to wear off," Trump told supporters at an event in South Carolina this weekend.

Poll shows two thirds of Americans think Biden is not fit for a second term

"And then he walks off. You ever notice how he goes like this?" Trump asks before mimicking the president's oddly stiff movements and difficulty with finding his way off stage.

Trump's performance came just weeks after Special Counsel Robert Hur said in a report that Biden's diminished mental state would make it difficult to prosecute him for mishandling classified documents.

Meanwhile, a Quinnipiac University poll from last week found that nearly two-thirds of Americans believe President Biden does not have the requisite mental fitness for a second term in office.

Although Biden attempted to push back on Hur's assertion by holding a White House press conference, the effort was undermined when he at one point mixed up the presidents of Egypt and Mexico.

White House aide blames press for unfavorable coverage

An Associated Press article noted that White House aide Ian Sams sent a letter to the White House Correspondents' Association complaining about how Hur's report had been covered.

For her part, NBC News reporter and White House Correspondents' Association president Kelly O'Donnell reacted angrily to Sams' letter.

"It is inappropriate for the White House to utilize internal pool distribution channels, primarily for logistics and the rapid sharing of need-to-know information, to disseminate generalized critiques of news coverage," the Associated Press quoted her as saying.
