“The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion”
US Constitution, Article IV, Section 4
Trump swore to uphold the Constitution and so did the judges and every person who has served in Congress.
No treaty, statute or judicial opinion can override a Constitutional imperative.
