WASHINGTON (AP) By the time President Donald Trump first spoke publicly about the coronavirus , it may already have been too late.

Interviewed at Davos, a gathering of global elites in the Swiss Alps, the president on Jan. 22 played down the threat posed by the respiratory virus from China, which had just reached American shores in the form of a solitary patient in Washington state.

We have it totally under control, Trump said on CNBC. Its one person coming in from China, and we have it under control. Its going to be just fine.

In the 11 weeks since that interview, the coronavirus has reached every corner of the globe. It has infected more than 500,000 Americans and killed at least 20,000. It has rewritten the rules of society, isolated people in their homes, closed schools, devastated the economy and put millions out of work.

When Trump spoke in Switzerland, weeks worth of warning signs already had been raised. In the ensuing month, before the president first addressed the crisis from the White House, key steps to prepare the nation for the coming pandemic were not taken.

Life-saving medical equipment was not stockpiled. Travel largely continued unabated. Vital public health data from China was not provided or was deemed untrustworthy. A White House riven by rivalries and turnover was slow to act. Urgent warnings were ignored by a president consumed by his impeachment trial and intent on protecting a robust economy that he viewed as central to his reelection chances.

Twenty current and former administration officials and Republicans close to the White House were interviewed for this account about the critical weeks lost before the president spoke to the nation on Feb. 26. Most spoke on condition of anonymity because they were not authorized to speak publicly about private discussions.
