Admiral Dr. Brett Giroir, the assistant secretary for US Department of Health and Human Services, acknowledged that "testing is tight" for Covid-19.

"There's no question that testing is tight, but there are enough tests out there for people who need the test to get the test," Giroir said on the "Today" show this morning.

"We are really going hospital to hospital to try to assure that the tests are available and I'm meeting with hospital associations from all the metroplex areas," Giroir added.

He said there would be "a million-plus" tests this week.

"We are not going to have tens of millions of tests this week — but we will have a million-plus tests, plus all the thousands of hospitals who do their own tests. That should be efficient to take care of the load we're going to see this week."
