US First Lady Dr Jill Biden has undergone a medical procedure to flush out debris from a puncture wound on her left foot, her spokesman says.
Michael LaRosa said Dr Biden's foot was punctured while she walking on a beach in Hawaii last weekend, but it was "unclear what object caused the puncture".
After the procedure on Thursday at Walter Reed National Military Medical Center in Bethesda, Maryland, LaRosa said, "The wound is now clean, free of infection and it is anticipated that it will heal nicely."
President Joe Biden joined his wife at Walter Reed for the procedure. The Bidens were returning to the White House on Thursday night.
The incident occurred last weekend before Dr Biden's two official events in Hawaii, where she went after attending the start of the Olympics in Tokyo.
During her time in Hawaii, she visited a pop-up COVID-19 vaccination clinic in Waipahu and later joined military families for a barbecue at Joint Base Pearl Harbor-Hickam.
