Defense Department officials have declared the Pentagon Reservation “a safe place to work” because of downward trends in local infection rates and hospitalizations. But a Thursday email sent to defense reporters revealed that a journalist had tested positive for the coronavirus, as well as two others who attended the same briefing on June 25.

“The reporter is not a member of the ‘resident’ Pentagon press corps that works here on a daily basis, and was only here for the briefing,” the email sent to Pentagon journalists read.
