Pence sought to soften the Administration's message amid growing clamour from governors of both parties for a national testing strategy to help secure in-demand supplies like testing swabs and chemical reagents.
Trump said yesterday that he could use the Defence Production Act to compel one company to manufacture swabs.
"When it comes to testing, we're here to help," Pence told governors during a videoconference from the headquarters of the Federal Emergency Management Agency. AP obtained audio of the call.
Pence said the Administration sent an email to officials today detailing current testing capacity by state.
But Maryland's Republican Governor Larry Hogan said much of the unused lab machinery listed for his state by the Administration was in federal labs that the state does not have access to. Pence agreed to open up federal labs to help states.
In Kansas, officials have said they would like to do 15,500 additional tests to sample the population to determine the prevalence of the coronavirus. Kansas has about half the national testing rate.
Kelly said part of the problem has been caused by how FEMA has gone about distributing testing material and other supplies.
In Ohio, Republican Governor Mike DeWine said his state is working with another federal agency, the Food and Drug Administration, to find a source of reagent, the chemical used to analyse test results, so it can ramp up testing.
"A lot of good things are going on, but we're not there yet," DeWine said. "And we've got a ways to go
Democratic Montana Governor Steve Bullock said his state received 5000 nasal swabs today from FEMA — evidence the federal Government is listening. But he added: "It doesn't get us far enough."
In New York, Democratic Governor Andrew Cuomo, whom Trump has vacillated between praising and criticising, said the states should take the lead on testing but it's up to the federal Government to help sort out supply chain issues facing testing manufacturers.
"What the states will run into is when you talk to those labs ... they buy machines and equipment from national manufacturers," Cuomo said.
"And those labs can only run as many tests as the national manufacturers provide them chemicals, reagents and lab kits."
Pennsylvania's Democratic Governor Tom Wolf said: "We need the reagents, we need the test kits and I think that's the sort of general cry from other states."
From Michigan, Democratic Governor Gretchen Whitmer said: "Robust testing is essential to have confidence about our strategies for safely reducing risk and re-engaging sectors of our economy. We're all needing swabs. We're all needing the reagents."
As Pence spoke with the governors, Trump took to Twitter with a more combative tone than his vice-president, complaining that the "radical left" and "Do Nothing Democrats" were playing politics with their complaints about a lack of tests.
The President in recent days has repeatedly compared governors' concerns about a lack of screening capacity to earlier complaints that the states did not have enough ventilators to keep up with the federal Government's projections of individuals who would become hospitalised during the virus outbreak.
"Now they scream ....'Testing, Testing, Testing,' again playing a very dangerous political game," Trump tweeted.
"States, not the Federal Government, should be doing the Testing - But we will work with the Governors and get it done. This is easy compared to the fast production of thousands of complex Ventilators!"
Public health experts say the country needs to dramatically increase its testing infrastructure if it is going to safely roll back restrictions and reopen businesses without risking a major spike in infections that would negate weeks of social distancing and economic strife.
Dr Anthony Fauci, the nation's top infectious diseases expert, told ABC that the country is currently running about 1.5 million to 2 million tests per week.
But, "we really need to get up to, at least, you know, maybe two times that, three times that."
Administration officials have insisted that the US currently has enough testing capacity to safely implement "Phase One" of a plan they released last week to begin a slow return to normality.
And they have argued that states could be running twice as many tests as they are now if only they were using all the equipment they already have access to.
Testing was an issue on Capitol Hill, too, where the Trump Administration and Congress were inching towards an agreement on an aid package of more than US$450 billion to boost a small-business loan programme that has run out of money.
The deal is expected to add funds for hospitals and Covid-19 testing, as well.
For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks.
But for some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia and death.
