False. Trump referred to "politicizing" of the coronavirus by Democrats as "their new hoax." He did not refer to the coronavirus itself as a hoax or call it fake. You can criticize that he did not take it seriously enough to shut down the economy sooner, and that'd be fair, but he did shut down air travel from China on Jan 31, for which he was shat on at the time, as usual. Had he not done that, we'd be dealing with 10x the number of cases now.
