How quickly we forget. Remember all the hullabaloo this Spring where everyone from Constitutional experts to Governors all climbed on Trump and said that he did not have the power to open up the states? Well that would also mean that he doesn't have the power to shut them down. Frankly many Governors orders have been thrown out by the courts 'cause they didn't go through their respective legislatures. Trump did not have the power to shut any state down and if he did, the Trump haters would have climbed all over him and he likely would have been embarrassed in court.
