I had not heard of Congress having been briefed by the WH 6 weeks ago. But around the same time was when US airports started screening passengers arriving from China for people who had a fever, possibly Covid-19, an imperfect but quickly deployed measure. And it was 4 or 5 weeks ago that flights from the US to and from China were shut down, a shut-down currently scheduled to end March 30th, but, of course, could be extended if appropriate. There are two vaccines that have begun CDC testing - from vague highly filtered news reports to vaccines in test in just 2 months!
That's not "scrambling", that's swift action. And if one or more of the vaccines prove effective and are brought online quickly ... they'll be like bombs going off in the collective face of the Dems and their MSM-shills who decided to Katrina-ize Covid-19 instead of working with President Trump's Administration to avert the disaster the Dems and MSM currently hope for.
