Trump went to great lengths to make sure this is a EUA, so it cannot be mandated.
So this seem like a red line that has been crossed for several reasons.
My prediction: It will come out (through whistle blowers) not only has a lot of adverse data been suppressed, but the original clinical trial was falsified (scant as it was) and that would bring a whole new dimension to this.
Trump will come out and say "I was assured they followed all the law when they did their trials, thats why I pushed for EUA."
At this point, all the events will converge and we will get what we have been waiting eagerly for - Finally some peace.
Durham will do what he has to do, when he has to do.
