As the Senate gears up to consider President Donald Trump's Supreme Court nominee Neil Gorsuch, Senate Minority Leader Chuck Schumer, D-N.Y., predicted Sunday that "it looks like Gorsuch will not reach the 60-vote margin" needed to overcome a filibuster. If the 60 votes aren't there, Schumer argued during an appearance on "Meet The Press," President Trump should gather with Senate Democrats and Republicans to "try to come up with a mainstream nominee. Look, when a nominee doesn't get 60 votes, you shouldn't change the rules, you should change the nominee." More from NBC News: Vast Wealth Held By Trump's Top Aides, Documents Show

Rise in Hate Crimes Spurs States to Enhance Protections In 2013, then-Democratic Senate Majority Leader Harry Reid made an unprecedented change in Senate rules to use the "nuclear option" and set a 51-vote threshold for Cabinet appointees and most judicial nominees, rather than 60 votes. Meanwhile, Senate Majority Leader Mitch McConnell, R-Ky., projected that it was possible this week that the Senate could take that one step further and force the rule changes to impact Supreme Court nominees.

Asked on Sunday's "Meet The Press" about whether he has enough votes to change the rules for a filibuster, McConnell said, "What I can tell you is that Neil Gorsuch will be confirmed this week. How that happens really depends on our Democratic friends. How many of them are willing to oppose cloture on a partisan basis to kill a Supreme Court nominee?" Any senator could object or keep talking to delay a vote — a filibuster. So, to overcome a filibuster, the Senate needs to scrap together 60 votes for cloture, which allows the Senate to schedule a vote on the nominee. If there aren't 60 votes, McConnell could use the "nuclear option," changing Senate rules so only 51 votes would be necessary to confirm the nominee. Two Democratic senators have announced that they would vote for cloture and to support Neil Gorsuch on the Supreme Court: Sen. Joe Manchin, D-W.V., and Sen. Heidi Heitkamp, D-N.D. Both senators are running for re-election next year in a state that President Trump won by a wide margin. But Gorsuch needs eight Democrats to cross over and vote with Republicans to reach 60 votes. Meanwhile, Democrats still harbor frustrations that President Obama's nominee to fill the seat last year, Judge Merrick Garland, was never offered a hearing when he was nominated last year after the death of Supreme Court Justice Antonin Scalia. McConnell said he has no regrets about Republican decisions not to hold a hearing or a vote on Garland because the vacancy occurred during an election year, and he also declined to answer a question on whether that precedent should be set into a resolution.
