>> thanks for having me. yes, we do need to increase capacity but i think most important is deploying it effectively as well. i think just to randomly test, of course, is not necessarily optimizing resources. i think we need to test but we also need to test wisely. david: way back in march, you wrote a piece that overregulation was inhibiting testing, that there were so many regulations affecting tests that it was just clogging up the whole system. they are bringing new testing methods online. have those roadblocks been removed? >> oh, yeah. we got off to a slow start but what we have accomplished is truly remarkable. once the private sector was freed up to test, we had an explosion in testing. we have done at least according to one source, almost 55 million tests in this country. that is unprecedented for a new disease. it's actually a remarkable accomplishment. david: it is indeed.
