Based on Trump's various other earlier statements that turned out to be inaccurate, there is a high likelihood that also his coronavirus numbers didn't reflect the latest situation.
Are you really serious? He was standing with memebers of the CDC and had just finished a meeting with a much larger group. One would think they would have the most up to date information. So in your world, Trump, having just finished meeting on the topic and standing with the members of the team, just made it up, instead of the New York Times using a number from an unknown time frame writing to make Trump look bad.
OK, if thats your story so be it. Not a very good look for you.
