Excellent timeline...nice work.
I had originally stated:
February 15, 2020 Trump declares national emergency
And also:
Trump declared national emergency Feb 15. 46 days after WHO notified by China 25 days after first known US case. 14 days BEFORE first US death
The truth is:
February 15 Trump declared national emergency, to circumvent the wall with Mexico not being built.
Not about Covid-19
That was March 13
Trump declared national emergency Feb 15. March 13
73 days after WHO notified by China
52 days after first known US case.14 days BEFORE first US death
13 days after the first death
