At Sunday’s coronavirus task force briefing, President Trump said he might use the Defense Production Act to compel the production of more swabs for testing, with capacity expected to increase by more than 20 million swabs each month.

The announcement comes as the governors of several states have called for the federal government to help them secure more supplies so they can meet the recommended requirements for gradually reopening their economies.

White House officials did not respond to requests for details about how the measure would be implemented, and as of Sunday evening, there was no official paperwork released showing that the Defense Production Act had been invoked for swabs.

Trump said officials are “preparing” to use the law to increase swab production at one U.S. facility, which he did not identify. “We’ve had a little difficulty with one,” he said.

“So we’re going to call in — as we have in the past, as you know, we’re calling in the Defense Production Act, and we’ll be getting swabs very easily,” he added. “Swabs are easy. Ventilators are hard. Ventilators are a big deal, and we are now the king of ventilators.”

Trump invoked the Defense Production Act last month to compel General Motors to manufacture ventilators to help handle the surge of coronavirus patients. According to the Department of Health and Human Services, more than 6,000 of the ventilators are expected to be delivered by June 1, with the remaining 24,000 on track to be delivered by the end of August, months after an anticipated peak in need has passed.

Amid mounting criticism — Gov. Ralph Northam (D) of Virginia on Sunday called the Trump administration’s claims of sufficient resources “delusional” — the president continued to defend his approach to testing, reiterating that it should be a “local thing.” He said Vice President Pence will hold a call Monday with governors on “what more they can do and do together to develop locally tailored testing strategies.”

Trump added, though, that he wants to help states procure testing materials.
