So they're illegal then?
Trump was only able to enact these tariffs without sign off from Congress (which he would absolutely not get) because they were enacted under the International Emergency Economic Powers Act. The act allows the president to apply certain controls over the economy so long as they're in response to a national emergency. At some point a while back either Trump or Biden, I forget which, declared a state of emergency over fentanyl. Trump is now using the tiny trickle of fentanyl coming from Canada as his justification for these tariffs because has to connect them to a state of emergency to enforce them.
If they're actually about making America richer (no matter how wrong he is about how that works) then they need approval by congress to go into force. Every single affected business in America should have standing to sue over that.
