In the The Washington Post:

"U.S. intelligence agencies issued warnings about the novel coronavirus in more than a dozen classified briefings prepared for President Trump in January and February, months during which he continued to play down the threat...

The repeated warnings were conveyed in issues of the President’s Daily Brief, a sensitive report that is produced before dawn each day...

For weeks, the PDB... traced the virus’s spread around the globe, made clear that China was suppressing information about the contagion’s transmissibility and lethal toll...

But the alarms appear to have failed to register with the president, who routinely skips reading the PDB and has at times shown little patience for even the oral summary he takes two or three times per week..."
