Can I ask an admittedly unlikely hypothetical?

The America President after doing something massively popular just after winning a landslide re-election tables legislation for the 2 terms in office to be relaxed. His minions in the houses are so elated they pass the motion.

What would then happen?

Does the Supreme Court step in and if required ask the military to step in, or does the Commander In Chief of the military command them as it was democratically decided? Could the Prez then remove the Supreme Court for acting against the democratic process?
