Pence said Wednesday 432,000 people had been tested, though the numbers did not include private testing facilities.

Dr. Deborah Birx, the coordinator of the White House coronavirus task force, said based on current data, there is no indication that the virus could infect a huge majority of Americans.

2:08 p.m.: AG urges federal prisons to explore releasing more inmates to early home confinement

Amid concerns of the potentially devastating effects that a COVID-19 outbreak could have within the walls of the nation's prisons, Attorney General William Barr said he has issued new recommendations to the Bureau of Prisons to explore releasing certain at-risk prisoners to home confinement to reduce the prison population.

Of the 146,000 inmates serving time in federal prison facilities, one-third are considered to have preexisting medical conditions and roughly 10,000 are over the age of 60, Barr said at a news conference on Thursday.

"You want to make sure that our institutions don't become petri dishes and it spreads rapidly through a particular institution. But we have the protocols that are designed to stop it and we are using all the tools we have to protect the inmates," Barr said.

Among those tools "will be identifying vulnerable prisoners who would make more sense to allow to go home to finish their confinement," he said.

Anyone who would be considered eligible for release to home confinement would have to quarantine for 14 days, he said.

In a phone interview with ABC News after the news conference, Barr stressed that there would be significant limits on what would make prisoners eligible for release to home confinement, noting that they could not be convicted of violent crimes or sex offenses -- which makes up roughly 40% of the over-60 population.

12:04 p.m.: Stimulus bill 'failed to meet the governmental need,' Cuomo says

New York Gov. Andrew Cuomo says Congress' $2 trillion stimulus bill has "failed to meet the governmental need."

Out of the total stimulus bill, New York state gets $5 billion for COVID-19 expenses, which Cuomo said does not help with lost revenue to the state.

"I'm disappointed," Cuomo said on Thursday. "I find it irresponsible. I find it reckless. Emotion is a luxury. And we don't have the luxury at this time of being emotional about what they [Congress] did. When this is over, I promise you I'm going to give them a piece of my mind."

"This was the time [for Congress] to put politics aside," Cuomo said. "Now is a time to actually step up, do the right thing, and do your job. And they haven't as far as I'm concerned, especially when it comes to the governmental need."

New York has become the nation's epicenter of the pandemic. The state has seen 385 deaths from COVID-19 and that number is expected to continue to rise, Cuomo said.

Over 37,000 New Yorkers have been diagnosed with the coronavirus and 5,000 of those people are in the hospital, he said.

As of Wednesday, New York was performing 25% of the COVID-19 testing nationwide, according to the governor.

Cuomo said the state has enough personal protective equipment for the immediate future.

New York is focusing on helping hospitals increase capacity by at least 50%. Officials are also scouting dorms and hotels for emergency beds.
