Checkup finds Joe Biden 'vigorous'; Kamala Harris in power for over an hour

Kamala Harris was — for one hour and 25 minutes — acting president while Joe Biden was under anesthesia

President Joe Biden remains “healthy” and “vigorous” and fit for duty, but is showing some signs of aging, his doctor said Friday after the oldest president in American history underwent his first routine physical in office and — in a history-making moment — while he underwent a colonoscopy.

Ms. Harris, the first woman, first Black person and first person of South Asian descent to be vice president, was — for one hour and 25 minutes — acting president while Mr. Biden was under anesthesia.

Over more than five hours Friday at Walter Reed National Military Medical Center, the President underwent a battery of blood, physical, gastrointestinal, dental, vision and neurological examinations. Dr. Kevin O'Connor, who has been Mr. Biden's primary care physician since 2009, wrote in a six-page memo released by the White House that Mr. Biden, who turns 79 on Saturday, “remains a healthy, vigorous, 78-year-old male, who is fit to successfully execute the duties of the Presidency.”
