President Trump defended federal coronavirus testing efforts and pledged to further help governors Sunday amid a bitter clash with several state leaders who say they desperately need more tests if Trump wants them to re-open for business.

“If they want it, we should give it to them and get it for them and work with them,” Trump said Sunday night regarding additional testing, pointing out the country has tested 4.1 million. Trump once again insisted “testing is a local thing,” even as governors have complained that they haven’t been able to obtain vital testing components.

“Every governor in America has been pushing and fighting and clawing to get more tests, not only from the federal government, but from every private lab in America and from across the world,” Maryland Gov. Larry Hogan, a Republican, said on CNN’s “State of the Union” Sunday. “It’s nowhere near where it needs to be.”

The president, who wants states to re-open in an effort to rehabilitate the faltering economy, said federal officials will send out 10 million more swabs a month and Vice President Mike Pence will speak to governors Monday to address any other needs.

Trump also plans to send governors a detailed list of private and academic laboratories that could be producing tests that currently aren’t in full use.

“We’ll get it done,” he said. “The biggest tester in the world will be very happy soon.”

The testing skirmish comes as Bay State officials are in the middle of a coronavirus surge. Gov. Charlie Baker touted his plan to increase testing and closely track each COVID-19 case while on CBS’s “Face the Nation” Sunday, saying contact tracing is key to re-opening Massachusetts.

“The goal here is to push back on the virus, the same way they did in South Korea, to contain it, understand where it is, and control it,” Baker said while on “Face the Nation” Sunday. “And I think it’s going to be critical for every state that wants to get ‘open’ and back to something like a new normal to put some kind of mechanism like this in place.”

Trump and governors have battled since last week, when Trump originally insisted he alone could declare when businesses and schools re-open. Trump later reversed his stance, prompting an outraged New York Gov. Andrew Cuomo to blast the president for not providing enough federal aid.

Trump clearly sought to make amends during his daily coronavirus update Sunday night, however. He thanked the New York Democrat for a great partnership.
