Trump doesn't deserve all the blame, but first and foremost his messaging was - and continues to be - horrid.
He does deserve the blame for leaving the stockpile empty 75% into his first term, and for bungling new testing needs, which was on his administration.
And finally, telling states they were on their own to get supplies, then confiscating supplies to renew the stockpile...........
In regards to calling COVID19 a hoax, he didn't do that. But what did the people at his rally think he was referring to? Esp when you consider what his messaging was at his daily pressers in front of the WH..........Trump has always resists giving in when he thinks he is right.
