President Donald Trump on Wednesday urged Senate Republicans to "go nuclear" and invoke a rule change to force a simple majority vote toward confirmation if Democrats block his U.S. Supreme Court nominee, Neil Gorsuch, as Democrats maneuvered for a tough fight.

Gorsuch and Vice President Mike Pence met with Senate Majority Leader Mitch McConnell, a day after Trump nominated the federal appeals court judge from Colorado for a lifetime job on the nation's highest court.

Trump's fellow Republicans control the Senate 52-48. Democrats signaled on Wednesday that they would set up a procedural hurdle, known as a filibuster, that would require 60 votes, rather than a simple majority, to move toward confirmation of Gorsuch.
