The truth of it is still scandalous. Does it absolve Trump of responsibility for idiots drinking disinfectant? At least partially, yes. It's still a ridiculous way for a leader to behave.
It's absurd that Trump thought he was in a position to give technical advice to medical researchers, and it's even more absurd that he thought injecting disinfectant could be the way to go. The hubris and ignorance on display here are shocking.
