SACRAMENTO — California will put forward a strategy Tuesday for gradually releasing residents from stay-at-home orders and allowing public life to resume amid the coronavirus pandemic.

Gov. Gavin Newsom said Monday that he has been developing a framework for the past week with the governors of Oregon and Washington that will allow the three states to incrementally reopen their economies as the spread of the virus appears to slow.

Their plan will be driven by facts, evidence and public health advisers, Newsom said. Notably not mentioned as a consideration was President Trump, who wants a quick reopening and emphatically restated Monday his belief that it is up to him, not individual states or cities, to decide when society gets moving again.

“We began a process of establishing more formally what it would look like,” Newsom said at a news conference, “using science to guide our decision-making, not political pressure, and continuing to do what we can to share our best practices and share our resolve.”

Newsom made his announcement as Trump repeated his belief that a president’s “authority is total” to decide when lockdown measures are lifted.

“For the purpose of creating conflict and confusion, some in the Fake News Media are saying that it is the Governors decision to open up the states, not that of the President of the United States & the Federal Government. Let it be fully understood that this is incorrect,” he tweeted Monday morning. “It is the decision of the President, and for many good reasons.”

Although he added that he would consult with governors on his decision, Trump later said at an evening news conference that he had not yet done so.

“You know why? Because I don’t have to,” he said. Trump suggested that governors who did not follow his lead could face political consequences.

“If some states refuse to open, I would like to see that person run for election,” he said. “They want to open, they have to open.”

All stay-at-home orders during the pandemic have been issued by state and local governments, not the Trump administration. Newsom has lately suggested that successful efforts to slow the spread of the coronavirus could mean he has to keep California shut down longer than the target date of early May that Trump has set.

On Friday, Newsom told CNN anchor Anderson Cooper that the social distancing efforts of Californians had “stretched” the curve of new infections into a more gradual increase and decline. He said it was “still too early to say” when he might be able to lift his statewide lockdown measures, which now run through May 3.

“I get the incredible power and potency of his voice,” Newsom said on CNN. “But at the end of the day, the practical application of that reality is at the state level.”

Reinforcing that point, the governors of Connecticut, Delaware, New Jersey, New York, Pennsylvania and Rhode Island announced their own coalition Monday to coordinate ending shelter-in-place policies.

At his news conference, Trump said states can’t do anything without his approval.

“The president of the United States calls the shots,” he said. “When somebody’s the president of the United States, the authority is total and that’s the way it’s gotta be. It’s total. It’s total. And the governors know that.”

But constitutional scholars disagree. Bernadette Meyler, a professor of constitutional law at Stanford Law School, said governors retain authority to order their residents to stay at home through the 10th Amendment, which reserves to the states and the people any powers not specifically delegated to the federal government in the Constitution.

The Public Health Service Act of 1944 does give the federal government some ability to quarantine people entering the U.S. from other countries or traveling between states to stop the spread of infectious diseases, Meyler said. But Trump is otherwise limited to publicly pressuring governors to follow his lead, she added.

“There’s really no authority that the president has to override the state quarantines,” Meyler said.

So far, everyone is playing nice. Trump said last week that Newsom has “done a very good job” on coronavirus response, and he included a clip of Newsom praising the president in a video that his staff assembled for Monday’s news conference.

Newsom, a frequent foe of Trump in his first year in office, has been nothing but complimentary of the assistance California has received from the federal government during the pandemic. He said Monday that he has “all the confidence in the world moving forward that we’ll maintain that collaborative spirit.”

With coronavirus hospitalizations thus far less than the state projected, Newsom said, California is entering the next phase of the crisis: suppression.

The strategy he plans to lay out Tuesday will not provide a specific timeline, he said, but rather “the questions that we are looking to ask and get answered at every level of government” before moving forward.

The state, Newsom said, must “figure out a way of doing this where we don’t invite a second wave, where we don’t let down our guard and we don’t put ourselves in a position where we regret moving too quickly.”
