The officers are members of an elite military unit dedicated to the White House and often work very close to the president and the first family. Trump was upset when he was informed on Wednesday that the valet had tested positive, a source told CNN, and was then tested again by the White House physician.
In a statement, the White House confirmed CNN's report that one of the president's officers had tested positive.
"We were recently notified by the White House medical unit that a member of the United States military, who works on the White House campus, has tested positive for Coronavirus," White House Deputy Press Secretary Hogan Gidley said in a statement. "The president and the vice president have since tested negative for the virus and they remain in good health."
A White House source said a valet, an unidentified man, showed "symptoms" Wednesday morning, saying that the news that someone near Trump had tested positive for coronavirus "hits the fan" in the West Wing.
