The internal WH memos reported in the NY Times and obtained by Axios compared to what was said publicly:

From the same memo: warning of the R naught estimates. The President banned many (but not all) travelers from China two days later.

This is from Feb. 23. It suggests the possibility of 2 million American deaths, 100 million infections. This is 3 days before Pres. Trump said “when you have 15 people, and the 15 within a couple of days is going to be down to close to zero, that's a pretty good job we've done”
