Most countries did try to prevent the plague slightly more than the US did. The “shutdown” was probably more about schools being closed for a few weeks/months and young men getting turned insane by youtube propaganda / anti-woke grifters.
You don’t even need to revoke the entire law. Just pass a resolution saying that the crisis that Trump uses as a legal basis is over (or that he made it up), which should theoretically dissolve his legal ability to enforce the tariffs. Of course, this is speaking from a lawyer POV, which trump has shown the correct amount of respect for until now (none).
I live within walking distance of my job (litterally 200 meters, so takes me almost as long to walk to the building as it takes me to walk to my chair from the entrance) and I’ve still had to talk to my boss about management’s idiotic decision to start clamping down on WFH, despite my department suffering massively from people quitting (down like 4 people this year, and total headcount is now less than 20, closer to 15)
To add to your last paragraph, you shouldn’t underestimate just how much the current crop of republican reps. derive their power from being near Trump. Like, obviously the house reps are all ghouls, but it seems like a solid chunk of them now just consider themselves Trumpists primarily, and anything going against trump is considered political suicide to such an extent that nobody wants to go first.
