Which is why they’ll, probably, say a president has no immunity. Why would they let someone else have power over them?
If a president decides it’s a duty to just outright remove SCOTUS justices, there’s nothing to stop them.
This is why "breaking Congress" was the other pillar of McConnell's legacy. The pillar of "control the judiciary" doesn't work nearly as well without it
I actually partially agree with Gorsuch's trolly take that if Congress doesn't like the interpretations they can rewrite the law, except it ignores practical realities about how hard it is to pass laws, shorter legislative tenure, longer waits for rulings, etc.
