Trump treated COVID as a PR problem instead of a public health crisis. No one blames him for the creation of the virus. Just by memory, some of the things he did that made it worse were downplaying the seriousness at the outset, claiming it was a hoax, saying it would go away like a miracle, claiming it would be gone by easter, comparing it to the flu and calling it kung flu, hosting super spreader events like his Tulsa rally and supreme court confirmation with disregard for protocols, resisting wearing a mask and mandates, resisting testing because it would add more cases, publicly questioning the CDC and Fauci and attacking their credibility, promoting unproven cures he got from a pillow salesman, attacking blue states and governors by withholding assistance and calling on his minions to liberate them, and blaming Obama for the pandemic because he gutted Obama's pandemic response team.
