TRENTON, N.J. (CBS/CNN) — The Centers for Disease Control and Prevention issued a travel advisory urging people in New York, New Jersey and Connecticut to “refrain from nonessential domestic travel” for the next two weeks. President Donald Trump had asked the CDC on Saturday to issue the advisory after he had floated the idea of a quarantine earlier in the day.

The CDC said this advisory does not apply to employees of critical infrastructure industries, including but not limited to trucking, public health professionals, financial services, and food supply. These employees of critical infrastructure, as defined by the United States Department of Homeland Security and have a special responsibility to maintain normal work schedules.

The move comes, he said on Twitter, after consulting with the governors of the three states, who will administer the plan “in consultation with the Federal Government.” The CDC said that the governors of the states would have “full discretion” on how to implement the advisory.

Trump said in his tweet that a quarantine would “not be necessary.”

Trump had said earlier in the day that he was considering a short-term quarantine of “hot spots” in parts of the tri-state area — New York, New Jersey and Connecticut — where cases of coronavirus continue to rise.

On Saturday, New Jersey Gov. Phil Murphy announced over 2,000 new COVID-19 cases, raising the statewide total to 11,124. New Jersey also has 140 coronavirus-related deaths.

“We’re thinking about certain things. Some people would like to see New York quarantined because it’s a hotspot. … We might not have to do it, but there’s a possibility that sometime today we’ll do a quarantine, short-term, two weeks on New York. Probably New Jersey, certain parts of Connecticut,” he told reporters as he departed the White House for Norfolk Naval Station to send off a Navy hospital ship to New York.

Trump’s suggestion comes after the United States this week became the epicenter of the global pandemic, with more than 120,000 reported Covid-19 cases across the country, and more than 52,000 of them in New York state alone. Officials forecast that the apex of the pandemic there is still 14 to 21 days away. But overwhelmed hospitals, in New York as well as across the US, working to treat coronavirus patients and curb the spread of the virus are facing a shortage of supplies and ventilators, a key piece of equipment.

New York Gov. Andrew Cuomo said that he spoke with Trump on Saturday morning, but that the two had not discussed a quarantine.

“I don’t even know what that means. I don’t know how that could be legally enforceable,” the Democratic governor said during in a news conference in Albany. “And from a medical point view, I don’t know what you would be accomplishing.”

“But I can tell you, I don’t even like the sound of it,” he added.

Later Saturday, Cuomo told CNN’s Ana Cabrera that the quarantine sounded more like a lockdown for the New York area, calling a potential move by the federal government “mayhem.”

“It would be chaos and mayhem,” Cuomo said. “It’s totally opposite everything he’s been saying. I don’t think it is plausible. I don’t think it is legal.”

Trump, however, earlier said that possible quarantine would be “enforceable” and “restrict travel” from those parts of the tri-state area. He also said any quarantine wouldn’t affect truckers from outside the New York area.

“Restrict travel, because they’re having problems down in Florida, a lot of New Yorkers going down. We don’t want that,” he said.

Florida’s governor had mandated a 14-day self-quarantine or isolation period for travelers coming to Florida from airports in New York, New Jersey and Connecticut. According to media reports, wealthy New Yorkers have fled Manhattan for vacation homes in the Hamptons, the Catskills, the Poconos, Florida and Connecticut.

Florida Gov. Ron DeSantis said during a call with Trump, the President mentioned the possibility of a quarantine “around the New York City area.”

“There’s a lot of logistics involved and I think the President is well suited to figure that out,” DeSantis said during a Saturday briefing. “Whatever works I think we need to do.”

DeSantis said it’s not fair to Floridians “to just be airdropping in people from the hot zones, bringing infections with them.” He added that New York officials were working hard and doing a great job but people are “dispersing from there.”

Sen. Richard Blumenthal, a Democrat from Connecticut, responded to Trump’s tweet with one of his own, saying that the possible quarantine measures are “unclear” and could cause “confusion.”

The specifics & impact of this new directive by tweet are unclear & uncertain. The effect may be more confusion than confidence. Gov. Lamont has been strong & effective in his leadership instructing CT’s people to self-quarantine & stay at home if possible,” Blumenthal said in a Saturday Twitter post.

As he departed from Joint Base Andrews, Trump said he would speak to Cuomo later about the possible quarantine. And describing the quarantine as something that would be “for a short period of time, if we do it at all,” the President also said that he would not close the New York City subway.

Earlier this month, Cuomo had deployed the National Guard and created a 1-mile “containment zone” in New Rochelle, a suburb of New York City, in an attempt to stop a growing cluster of coronavirus cases.

The National Guard helped coordinate delivering meals to those in quarantine and a drive-thru coronavirus testing site was opened.

Cuomo said that the number of new coronavirus cases slowed over the period the restrictions were imposed.

As of Saturday morning, New York had at least 728 reported deaths due to coronavirus and at least 52,318 reported cases — making it the state with the most in the nation, according to CNN Health’s tally.
