During the past two months, I have had lengthy conversations with some 30 scientists, health experts, and past and current government officials—all of them people with firsthand knowledge of what our response to the coronavirus pandemic should have been, could have been, and actually was. The government officials had served or are still serving in the uniformed military, on the White House staff, or in other executive departments, and in various intelligence agencies. Some spoke on condition of anonymity, given their official roles. As I continued these conversations, the people I talked with had noticeably different moods. First, in March and April, they were astonished and puzzled about what had happened. Eventually, in May and June, they were enraged. “The president kept a cruise ship from landing in California, because he didn’t want ‘his numbers’ to go up,” a former senior government official told me. He was referring to Donald Trump’s comment, in early March, that he didn’t want infected passengers on the cruise ship Grand Princess to come ashore, because “I like the numbers being where they are.” Trump didn’t try to write this comment off as a “joke,” his go-to defense when his remarks cause outrage, including his June 20 comment in Tulsa that he’d told medical officials to “slow the testing down, please” in order to keep the reported case level low. But the evidence shows that he has been deadly earnest about denying the threat of COVID-19, and delaying action against it…

What happened once the disease began spreading in this country was a federal disaster in its own right: Katrina on a national scale, Chernobyl minus the radiation. It involved the failure to test; the failure to trace; the shortage of equipment; the dismissal of masks; the silencing or sidelining of professional scientists; the stream of conflicting, misleading, callous, and recklessly ignorant statements by those who did speak on the national government’s behalf. As late as February 26, Donald Trump notoriously said of the infection rate, “You have 15 people, and the 15 within a couple of days is going to be down close to zero.” What happened after that—when those 15 cases became 15,000, and then more than 2 million, en route to a total no one can foretell—will be a central part of the history of our times.

But what happened in the two months before Trump’s statement, when the United States still had a chance of containing the disease where it started or at least buffering its effects, is if anything worse.
