Lockdowns, travel and gathering restrictions, mask mandates and the like are being dealt with by the states as directions under their respective public health acts. The High Court has already upheld the states' constitutional rights in that regard.
In any event, how would Federal legislation overriding state-based restrictions, like border closures or mask mandates, work? Those matters are being enforced, by and large, by state police. Are you going to send in the Army to stop the various state police enforcing state legislation?
