trump's purpose for doing as he's done,
First he ignores when a virus is coming , and refuses to do anything, then when others start doing good things he goes in and interferes to get the headlines and attention back on himself. He's used this tactic many times , refusing to help when asked but when others do well he goes out of his way to hurt their progress , and threatens them. He doesn't approve of anyone protesting him , but if it was for him he'd have police protecting them while they were allowed to do as they please, and with his protections. What its done is expose him as a weak and failing leader who can't handle one crisis let alone three of them we're facing now , and more coming. trump is not trying to make America Great Again, he's intentionally hurting this country to weaken it for himself to use to profit from it like a mobsters does. He would be killing protesters now if he thought he could get away with it.
