Trump talked about disinfectants and UV rays being potential salves for the virus. There is proof emerging that is the case. Specify why you think it was a blunder for him to say so.
Did he or did he not mention disinfectants and then the possibility of using them ‘inside the body’? That was a poor choice, rhetorically - especially considering how dumb the average viewer is. So, a rhetorical blunder, should have stopped after the UV light comments. Was he responding to a question? either way, should have said, “we are investigating all avenues” —much harder to spin.
