President Donald Trump lied Friday when he said he was being "sarcastic" when he asked medical experts on Thursday to look into the possibility of injecting disinfectant as a treatment for the coronavirus.

Doctors and the company that makes Lysol and Dettol warned that injecting or ingesting disinfectants is dangerous. But when Trump was asked about the comments during a bill signing on Friday, he said, "I was asking a question sarcastically to reporters like you just to see what would happen."

Trump said he was being sarcastic but he was not being "sarcastic" on Thursday when he raised the possibility of injecting disinfectant. There was simply no indication that he was being anything less than serious. He was also wrong Friday when he denied he had asked the medical experts to "check" the idea of disinfectant injections; he was looking at them at the time. And he did not mention hands during his Thursday remarks.
