Of course he knew it was coming!! It had been coming since the 90s!!! Anyone with a brain could see that we were on the cusp on a global pandemic with threats like SARS, bird flu, etc.
President Clinton started working on pandemic threat and Bush came into Office and continued the work and handed off Obama a plan to work with and build on.
Here's an article from The Atlantic that goes over, in excruciating detail, how pandemic response planning specifically against viruses of Chinese origin started in the Bush administration after the SARS and H5N1 bird flu outbreaks, and the Trump administration incompetently undermined these efforts by refusing to fill CDC posts in China amongst other dumb missteps.
Trump threw away a Bipartisan multi-administration plan to deal with something like COVID-19. What a brilliant and stable genius!
