President Trump lashed out at The New York Times over a story it published on Saturday that reported Health and Human Services (HHS) Secretary Alex Azar repeatedly warned the president of the possibility of a coronavirus outbreak weeks before his administration began to crack down in its response to the threat.

Trump denied the story in a Sunday night tweet, claiming it was “fake news” and that Azar told him “nothing” until after his office rolled out travel restrictions from China.

“The @nytimes story is a Fake, just like the ‘paper’ itself. I was criticized for moving too fast when I issued the China Ban, long before most others wanted to do so,” he tweeted.

“@SecAzar told me nothing until later, and Peter Navarro memo was same as Ban (see his statements). Fake News!” he added, referring to The Times’ reporting that White House trade adviser Peter Navarro had warned Trump of the possible consequences of an outbreak in a memo on Jan. 29.
