re: Katie Porter (d) wants Congress to police the Supreme Court

Actually, in issues where statutes are unclear, it absolutely is the job of Congress to pass laws that clarify how a given statute is to be enforced. Sometimes, SCOTUS will interpret a statute to mean one thing leading to Congress passing a law to change that statute so that is enforced the way they wanted SCOTUS to rule in the first place. This is what Congress is supposed to do.
