As for “Florida [deaths] are going down”:

We all knew Trump was lying and he knew he was lying at the point when he qualified his statement with "yeah :sidelook: It's going-- It leveled out and it's going down, that's my report as of yesterday." Trump saw an opening. His brain flashed: “Swan doesn’t have perfect information/recall and, even if he does, I can claim access to preferred knowledge.” It was just another version of “people are saying.”
Swan needed to do a Curb Your Enthusiasm stare-down: “Are you sure, Mr. President?”
