Talking at a round table on police reform in Dallas, Mr Trump darted across topics from hurricanes to oil to the coronavirus in the span of minutes before lingering on the pandemic when the pro-Trump crowd cheered in support.
"The supply [of oil] changed rapidly with Covid-19, or whatever you want to call it, I'd never heard so many names," Mr Trump said.
"You've got 30 names you can call this thing. I call it the plague from China. The plague."
At that point the audience broke out in wild approval, prompting the president to continue.
"And it's not good. And it's not good. It could have been stopped in China but they decided not to do that and we'll have to figure that one out won't we."
