This is odd. I’ve never heard of the president going to the Pentagon for a “fitness exam.” From the pool report:
From a WH official:
Today, the President is participating in a routine fitness evaluation at the Fit to Win Clinic located inside the Pentagon’s DiLorenzo TRICARE Health clinic. The fitness evaluation is part of the periodic medical exam that is coordinated by the Physician to the President. The results of the President’s periodic medical exam will be released before the end of the month.
Maybe it’s different from the usual physical exam a president gets at Bethesda Naval Medical Center. But as far as I’m aware, this is something new.
