President Biden has introduced a change to his White House departure and return routine. Instead of walking across the South Lawn to and from Marine One by himself, he's now often surrounded by aides.

Why it matters: With aides walking between Biden and journalists' camera position outside the White House, the visual effect is to draw less attention to the 81-year-old's halting and stiff gait.

Zoom in: Some Biden advisers have told Axios they're concerned that videos of Biden walking and shuffling alone — especially across the grass — have highlighted his age.
