(LIFEZETTE) Perpetual GOP malcontent Sen. John McCain (R-Ariz.) called lawmakers “stupid” who believed invoking the so-called “nuclear option” to confirm Judge Neil Gorsuch to the Supreme Court would ultimately improve the Senate, during a gaggle with reporters Tuesday.

McCain, a vocal and frequent critic of President Donald Trump, supports the president’s Supreme Court nominee and announced Monday that he would reluctantly back the use of the “nuclear option” to change Senate rules to require a simple majority of 50 votes to confirm Gorsuch.
