On Sunday, Admiral Brett Giroir, a member of President Donald Trump s coronavirus task force, refused to admit that the administration is not doing enough to boost testing capacity across the country.

At one point during an interview with CNNs Jake Tapper , he attributed widespread frustration over delayed tests to would-be travelers.

There is no evidence prospective travelers are responsible for the surge in tests; rather, the U.S. has the worlds highest number of coronavirus cases and deaths, and testing is one of the few ways to know how large the problem really is. But American laboratories responsible for processing coronavirus tests are buckling under demand for their services .
