Democrats on Monday amassed enough support to block a U.S. Senate confirmation vote on President Donald Trump's Supreme Court nominee, Neil Gorsuch, but Republicans vowed to change the Senate rules to ensure the conservative judge gets the lifetime job.

As the Judiciary Committee moved toward sending Gorsuch's nomination to the full Senate, Sen. Christopher Coons became the 41st Democrat to announce support for a procedural hurdle called a filibuster requiring a super-majority of 60 votes in the 100-seat Senate to allow a confirmation vote.

But Republican Senate leaders insist Gorsuch will be confirmed on the Senate floor on Friday regardless of what the Democrats do, even if they have to change long-standing Senate rules.
