President Trump declared the national emergency so I would say yes Brett is wrong.
However Trump has said he is working with the States, which is common sense.
That is, on this issue.
You like your doctor, you can keep your doctor. Dont tell me Trump dont have the power. Interstate trucking is the life line. Shut it down for three days and watch. Lots of power has never been used.
I also believe Trump can lift the national emergency. After that, the states who do not open will be forced to take total responsibility.
