Stricken by COVID-19, a feverish and fatigued President Donald Trump was flown to a military hospital Friday night after being injected with an experimental drug combination in treatment at the White House.

In a day of whipsaw events, the president who has spent months downplaying the threat of the virus was forced to cancel all campaign events a month before the election as he fought a virus that has killed more than 205,000 Americans and is hitting others in his orbit as well.

The White House said Trump’s expected stay of “a few days” at Walter Reed National Military Medical Center was precautionary and that he would continue to work from the hospital’s presidential suite, which is equipped to allow him to keep up his official duties.

Trump walked out of the White House Friday evening wearing a mask and gave a thumbs-up to reporters but did not speak before boarding Marine One. Members of the aircrew, Secret Service agents and White House staff wore face coverings to protect themselves from the president onboard the helicopter.

In a video taped before leaving for Walter Reed, Trump said, “I think I’m doing very well, but we’re going to make sure that things work out.” He remained fully president, all authority intact.
