Broad coronavirus testing crucial in lifting restrictions: U.S. experts

The United States needs to ramp up testing for the coronavirus as the White House considers when and how to lift stay-at-home restrictions and lockdowns triggered by the pandemic, U.S. health experts said on Sunday. More than 2 million tests have been done in the country so far, but the tests are not available to many who need them, said Dr. Stephen Hahn, commissioner of the Food and Drug Administration. "We need to do more, no question about that," Hahn said on ABC's "This Week."
