Hi, icd. Actually, the individual state's governors are the ones that have placed the totalitarian, fascist, unconstitutional "lockdowns" and "controls" in place.
The Congress, both houses, have that authority. However, the Executive Branch does not, unless martial law is actually declared.
The Congress hasn't done so. The Executive Branch hasn't done so.
It's the bloody governors, such as Nohio's (special emphasis upon the "No") that have taken it upon themselves, in an unconstitutional power grab, that have.
