President Joe Biden had a small slip on the stairs of Air Force One on Tuesday during his trip to rainy Michigan to visit the UAW strikers—just hours after an Axios report emerged, revealing that his campaign team was taking extra precautions in the 2024 presidential campaign to make sure he doesn’t slip up. Despite wearing work boots, his heel slipped close to the bottom of his descent but he caught himself before falling. After he was mocked for tripping over a sandbag in June at the Air Force Academy, and as many voters voice concerns in polls about his age, Axios reported Tuesday that Biden has been working on his balance with a physical therapist, performing regular exercises since late 2021. He has also been seen wearing tennis shoes to improve traction as a response to what he has been told is “a combination of significant spinal arthritis” and “mild post-fracture foot arthritis” by his doctor. It’s all part of what Axios described as an “urgent project to protect his re-election bid.” Biden’s spokesperson, however, said Axios’ article was part of “an unfortunate pattern” of media sensationalism “rather than covering the president’s very real achievements for hardworking Americans.”
