At the time of the procedure, Ms Biden’s press secretary, Michael Larosa, said: “FLOTUS underwent a successful procedure on her left leg to take out debris from a puncture wound.

“After medical staff inspected the wound, it is not clear what object caused the puncture.

“The wound is now clean, free of infection and will hopefully heal well.”

Even after the procedure, doctors were unable to identify what caused the injury.
