So far, we know the following have Covid:
Donald Trump
Melania
Hope Hicks
Ronna McDaniel
Kellyanne Conway
Bill Sepian
Fr. John Jenkins
Sen. Tom Tillis
Sen. Mike Lee
And more
Some of the possible spreader events: the SC justice nomination gathering at the WH, the debate prep room, the debate itself, the fundraiser attended by Trump after knowing Hicks tested positive, the WH press briefing in which no mention of Hicks' positive result was made.
Chris Christie spent days in the mask-less "room where it happened" with many of the above names prepping for the debate, and the White House hadn't contacted him, he found out he'd been exposed by watching the news. Such gross incompetence in the White House, such gross incompetence in the way the Trump administration has handled the crisis for the whole country. The Trump family watched the debate mask-less, against the rules of the Cleveland Clinic. They didn't care about the others in the room, they don't care about Americans, they only care about themselves.
