Who would have that information first, during that time? The "intelligence" agencies.
There is no way they were going to give Trump that info where had been publicly blaming the CCP, and being bashed by the media for it.
They weren't going to give him a victory after their 4+ year coup against him. They saw the virus as their way to remove him.
I’d be fine with that answer, want it on the table. Focus of 2nd Trump admin (please Heaven) should be destroying the deep state, forget the stock market and tax cuts.
