LOL.  That room is small - http://www.whitehousemuseum.org/west-wing/press-briefing-room.htm.  I'd be shocked if USSS wasn't testing already and had been for a while.  They know who is and isn't sick.  POTUS & Team are probably using some next gen prophylactic or other new tech method to protect themselves. A lot of reporters are gonna test positive and PDJT won't get sick. Won't waiver.  Will lead.
