And SECTION 2
The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority...
The USC embodies the laws of the United States and if they don't contradict the Constitution they're valid and the Supreme Court has the POWER to remove someone from office CONSTITUTIONALLY through legislation Congress itself passed.
It’s okay. You keep thinking that.
Let me know if there’s any examples of a federal civil officer being removed from office other than by conviction in an impeachment (other than being removed by the President in the case of a cabinet official being dismissed, etc)
