On June 15, 2020, Trump explained,

Our testing is so far advanced, it’s so much bigger and better than any other country that we’re going to have more cases, we’re always going to have more cases. And as I said this morning that’s probably the downside of having good testing, is you find a lot of cases that other countries who don’t even test, don’t have. If you don’t test, you don’t have any cases. If we stop testing right now we would have very few cases if any.

On the day of his comments, the United States had suffered 120,942 deaths from COVID-19, more than all American deaths during the First World War.

Trump also previously called testing “overrated” and spent the early months of the pandemic dismissing concerns about the growing crisis.
