Senate Republicans on Thursday defied Democrats and delivered a big win for President Trump, by voting to change Senate precedent in order to allow the confirmation of Trump’s Supreme Court pick.

Senate Majority Leader Mitch McConnell, R-Ky., invoked the so-called “nuclear option” after warning for weeks that he would take that step if Democrats chose to vote down Trump’s pick, Judge Neil Gorsuch. Democrats did just that shortly before noon on Thursday, which prompted McConnell to start the process of changing the process for Supreme Court picks.
