Yes, that does seem to be true:
Flanked by doctors in the White House's press briefing room, Mr Trump cited US Government research suggesting coronavirus could be killed off more quickly when exposed to sunlight, heat and humidity, and is destroyed altogether when hit by disinfectants.
"So, supposing we hit the body with a tremendous, whether it's ultraviolet or just very powerful light, and I think you said that has not been checked but you're going to test it," he said turning to some of the medical professionals present at the press conference.
"And then I said, supposing you brought the light inside the body, which you can do either through the skin or in some other way.
"And I think you said you're going to test that, too, sounds interesting.
"Right, and then I see the disinfectant, it knocks it out in a minute, one minute and is there a way we can do something like that by injection inside or almost a cleaning, cause you see it gets on the lungs and it does a tremendous number on the lungs."
Mr Trump's comments prompted British company RB, which makes Dettol and Lysol, to release a statement saying that "under no circumstances should disinfectant products be administered into the human body, through injection, ingestion or any other means".
