As if the CDC is going to come out and say ''hey guys, that test we've been using is crap, so we're going to abandon it and use this new one''.
That what real journalists do. I know it's been a long time since we're had much real journalism, but they investigate and try to get to the bottom of things rather than just sit back and accept as fact what's spoon fed to them by the people and organizations they're so desperate to support anyway (and spin things and flat out lie in order to attack the others they don't support).
Paul Craig Roberts has proved himself for decades. Fouci, the CDC political appointees, et.al. have also shown themselves for what they are over the past 2 years. His interpretation of the facts and their own comments makes sense and appears accurate.
