Senate Majority Leader Mitch McConnell said Tuesday that the Senate would "withhold" consent of President Obama's Supreme Court nomination, the most definitive statement he's made yet about whether the GOP-led Senate will take up Obama's nominee.

Speaking on the Senate floor, McConnell said the president who succeeds Obama should choose the nominee to replace Associate Justice Antonin Scalia, who died earlier this month.

"Presidents have the right to nominate just as the Senate has its constitutional right to provide or withhold consent," McConnell said. "In this case, the Senate will withhold it."

McConnell said the Senate has not taken up a Supreme Court nominee in the final year of a president's term in 80 years. He said the voters, not a "lame duck" president, should make the decision in who they choose as president.

He also cited the words of Sen. Chuck Schumer, D-N.Y., and Vice President Joe Biden, who in the past have said they opposed confirming nominations of outgoing presidents.

Minority Leader Harry Reid, D-Nev., followed McConnell onto the floor to criticize his stance on the nominee, who has yet to be chosen by Obama.

Reid said there is plenty of time for the Senate to consider a nominee and called it "an extremist approach propagated by the likes of Donald Trump and Ted Cruz."
