WASHINGTON – Each morning at 8 as the coronavirus crisis was raging in April, Mark Meadows, the White House chief of staff, convened a small group of aides to steer the administration through what had become a public health, economic and political disaster.

They saw their immediate role as practical problem-solvers. Produce more ventilators. Find more personal protective equipment. Provide more testing.

But their ultimate goal was to shift responsibility for leading the fight against the pandemic from the White House to the states. They referred to this as “state authority handoff,” and it was at the heart of what would become at once a catastrophic policy blunder and an attempt to escape blame for a crisis that had engulfed the country.

Over a critical period beginning in mid-April, President Donald Trump and his team convinced themselves that the outbreak was fading, that they had given state governments all the resources they needed to contain its remaining “embers” and that it was time to ease up on the lockdown.

In doing so, he was ignoring warnings that the numbers would continue to drop only if social distancing was kept in place, rushing instead to restart the economy and tend to his battered re-election hopes.

For scientific affirmation, they turned to Dr. Deborah Birx, the sole public health professional in Meadows’ group. A highly regarded infectious diseases expert, she was a constant source of upbeat news for the president and his aides, walking the halls with charts emphasizing that outbreaks were gradually easing.

On April 11, she told the coronavirus task force in the Situation Room that the nation was in good shape.

A sharp pivot soon followed, with consequences that continue to plague the country today.

Even as experts warned that the pandemic was far from under control, Trump went, in a matter of days, from proclaiming that he alone had the authority to decide when the economy would reopen to pushing that responsibility onto the states. The government issued detailed reopening guidelines, but almost immediately, Trump began criticizing Democratic governors who did not “liberate” their states.

Trump’s bet that the crisis would fade away proved wrong. But an examination of the shift in April and its aftermath shows that the approach he embraced was not just a misjudgment. Instead, it was a deliberate strategy that he would stick to as evidence mounted that the virus would continue to infect and kill large numbers of Americans.

He and his top aides would openly disdain the scientific research into the disease and the advice of experts on how to contain it, seek to muzzle more authoritative voices like Dr. Anthony Fauci and continue to distort reality even as it became clear that Trump’s hopes for a rapid rebound in the economy and his electoral prospects were not materializing.

Now interviews with more than two dozen officials inside the administration and in the states, and a review of e-mails and documents, reveal previously unreported details about how the White House put the nation on its current course during a fateful period this spring.

• Birx was more central than publicly known to the judgment inside the West Wing that the virus was on a downward path. Her model-based assessment failed to account for a vital variable: how Trump’s rush to urge a return to normalcy would help undercut the social distancing and other measures that were holding down the numbers.

• The president quickly came to feel trapped by his own reopening guidelines. States needed declining cases to reopen, or at least a declining rate of positive tests. But more testing meant overall cases were destined to go up, undercutting the president’s push to crank up the economy. The result was to intensify Trump’s remarkable public campaign against testing, a vivid example of how he often waged war with science and his own administration’s experts and stated policies.

• Trump’s bizarre public statements, his refusal to wear a mask and his pressure on states to get their economies going again left governors and other state officials scrambling to deal with a leadership vacuum.

• Not until early June did White House officials even begin to recognize that their assumptions about the course of the pandemic had proved wrong. Even now there are internal divisions over how far to go in having officials publicly acknowledge the reality of the situation.

Judd Deere, a White House spokesman, said the president had imposed travel restrictions on China early in the pandemic, signed economic relief measures that have provided Americans with critical assistance and dealt with other issues, including supplies of personal protective equipment, testing capacity and vaccine development.

At a briefing on April 10, Trump predicted that the number of deaths in the United States from the pandemic would be “substantially” fewer than 100,000. As of Saturday, the death toll stood at 139,186; the pace of new deaths was rising again; and the country, logging a seven-day average of 65,790 new cases a day, had more confirmed cases per capita than any other major industrial nation.

Trump’s choice

The president had a decision to make.

It was the end of March, and his initial 15-day effort to slow the spread of the virus by essentially shutting down the country was expiring in days. Sitting in the Oval Office were Fauci and Birx, along with other top officials. Days earlier, Trump had said he envisioned the country being “opened up and raring to go” by Easter, but now he was on the verge of announcing that he would keep the country shut down for another 30 days.

“Do you really think we need to do this?” Trump asked Fauci.

“Yeah, we really do need to do it,” Fauci replied, explaining again the federal government’s role in making sure the virus did not explode across the country.

Trump’s willingness to go along was a concession that federal responsibility was crucial to defeating a virus that did not respect state boundaries.

But even as the president was acknowledging the need for tough decisions, he and his aides would soon be looking to do the opposite: build a public case that the federal government had completed its job and unshackle the president from ownership of the response.

By mid-April, Trump had grown publicly impatient with the stay-at-home recommendations he had reluctantly endorsed. Weekly unemployment claims made clear the economy was cratering, and polling was showing his campaign bleeding support.

The issue was clear: How much longer do we keep this up?

To answer that, they focused on two more questions: Had the virus peaked? And had the government given the states the tools they needed to manage the remaining problems?

On the first question, Birx was optimistic: Mitigation was working, even as many outside experts were warning that the nation would remain at great risk if it let up on social distancing and moved prematurely to reopen.

The group believed they had succeeded on the second question, too, although shortages of protective gear continued in some places (and would flare again months later). A one-time anticipated shortage of more than 100,000 ventilators had been overcome; now there was enough of a surplus that the U.S. could lend them to other countries. A ban on elective surgeries meant there was plenty of bed space.

On testing, Trump shifted from asserting that the nation was already doing more testing than any other country to deriding its importance. By June the president was regularly making nonsensical statements such as, “If we stop testing right now, we’d have very few cases, if any.”

On April 10, Trump declared that it would be his decision about whether to reopen the country.

Days later, Birx and Fauci presented Trump with a plan for issuing guidelines to start reopening the country at the end of the month. Developed largely by Birx, the guidelines laid out broad, voluntary standards for states considering how fast to come out of the lockdown.

In political terms, the document’s message was that responsibility for dealing with the pandemic was shifting from Trump to the states.

On April 16, he made the message to the governors explicit.

“You’re going to call your own shots,” he said.

The consequences

Birx had assembled a team of analysts who fed her a constant stream of updated data, packaged in PowerPoint slides e-mailed to senior officials each day. But there were warnings that the models she studied might not be accurate, especially in predicting the course of the virus against a backdrop of evolving political, economic and social factors. Among the models Birx relied on most was one produced by researchers at the University of Washington.

Birx declined to be interviewed. A task force official said she had used the University of Washington’s model in only a limited way and that the White House used “real data, not modeled data, to understand the pandemic in the United States.”

But despite the outside warnings and evidence by early May that new infections remained higher than anticipated, the White House never fundamentally reexamined the course it had set in mid-April.

Instead, Birx regularly delivered what the new team was hoping for.

“All metros are stabilizing,” she would tell them, saying the virus had hit its “peak” around mid-April. The slope was heading in the right direction. She endorsed the idea that death counts and hospitalization numbers could be inflated.

The real-world consequences of Trump’s abdication of responsibility rippled across the country.

By early June, it was clear that the White House had gotten it wrong.

Digging into new data from Birx, they concluded the virus was in fact spreading with invisible ferocity during the weeks in May — when states were opening up with Trump’s encouragement.
