Dr. James Phillips, the Walter Reed physician who criticized President Trump’s decision to greet supporters outside the facility where he was being treated for COVID-19, has worked his last shift at the hospital. “I stand by my words, and I regret nothing,” Phillips wrote on Twitter…

Phillips, who is also the chief of disaster medicine at George Washington University, said in October that Trump’s insistence on riding in a motorcade past supporters gathered across the street from Walter Reed exposed his security detail and others to a high risk of infection by the deadly coronavirus.

“The irresponsibility is astounding. My thoughts are with the Secret Service forced to play,” the physician wrote, in a tweet that was later deleted. He also dismissed Trump’s outing — which came one month before the national election — as “political theater” that forced other people into quarantine and put them at unnecessary risk.
