The Marine assigned to Marine Helicopter Squadron One tested positive after flying to Bedminster, N.J., in advance of the president’s upcoming stay there this weekend.

The Marine Corps said that the service member, who is asymptomatic, was tested on July 21 and that the results came back on July 23. The Marine Corps said it is coordinating with the White House medical staff to perform contact tracing.

“Out of an abundance of caution, Marines who may have had contact with the infected Marine have been removed from the detachment,” the Marine Corps said in a statement to The Hill. “The infected Marine was never in direct contact with the President’s helicopter, Marine One.

...but hey, do what you want...you will anyway.
