USA states make their own laws. Sometimes those laws are challenged as "unconstitional" and then the Supreme Court evaluates and maybe tells them to stop. Most of the time not though. They prefer to "leave it up to the states". The recent OSHA ruling (attempt at broad vaccine mandates for Americans) for instance. The Supreme Court said they can't do that.
