Biden's precautions boarding Air Force One raise questions

President Joe Biden’s frequent use of the shorter ladder while boarding Air Force One has raised eyebrows, and a Secret Service agent’s position at the base of the stairs has prompted additional speculation.

Air Force One has two different ladders the president uses to board before flights. One is longer and allows the president to board to a higher point on the plane, while the other, with fewer steps, allows boarding to a lower point.
