Senate leaders are slated to hit the Sunday show circuit this week ahead of a likely showdown over President Trump's Supreme Court nominee Neil Gorsuch.

Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellGOP ramps up attacks on Democrats over talk of nixing filibuster MLB owner: It's 'very necessary' to vote for Trump Delta: Early departures saved flight attendants' jobs MORE (R-Ky.) and Senate Minority Leader Charles Schumer Chuck SchumerOvernight Health Care: Schumer calls for Azar to resign over 'chaos' in coronavirus response CNBC's Cramer calls Pelosi 'crazy Nancy' in live interview Schumer calls for Azar to resign over 'chaos' in coronavirus response MORE (D-N.Y.) are both scheduled to appear on NBC’s “Meet the Press” this Sunday.

Their appearances come after two Democrats – Sens. Heidi Heitkamp Mary (Heidi) Kathryn HeitkampCentrists, progressives rally around Harris pick for VP 70 former senators propose bipartisan caucus for incumbents Susan Collins set to play pivotal role in impeachment drama MORE (N.D.) and Joe Manchin Joseph (Joe) ManchinOVERNIGHT ENERGY: House Democrats tee up vote on climate-focused energy bill next week | EPA reappoints controversial leader to air quality advisory committee | Coronavirus creates delay in Pentagon research for alternative to 'forever chemicals' Senate Democrats demand White House fire controversial head of public lands agency House Democrats tee up vote on climate-focused energy bill next week MORE (W.Va.) – announced this week that they will back Gorsuch for the vacant seat on the nation’s highest court.

But Gorsuch's road to confirmation without changing the Senate rules grew increasingly difficult Friday when Sen. Claire McCaskill Claire Conner McCaskillDemocratic-linked group runs ads in Kansas GOP Senate primary Trump mocked for low attendance at rally Missouri county issues travel advisory for Lake of the Ozarks after Memorial Day parties MORE (D-Mo.) announced she would vote to filibuster Trump's nominee.

That leaves the number of Democrats who have undecided or unclear positions on Gorsuch at nine, according to The Hill's Whip List. Republicans need eight to overcome a filibuster.

Schumer told The Washington Post on Thursday that it was "virtually impossible" for Democrats and Republicans to reach an agreement on Gorsuch to avoid a showdown.

Under current rules, Republicans need 60 votes to confirm Gorsuch. Republicans hold 52 seats in the upper chamber, and Heitkamp and Manchin are the only two to have broken with their party to support him.

Republicans, gearing up for a potential vote next week, are weighing the so-called nuclear option, which would change the Senate rules so that only a simple majority would be required to confirm Gorsuch.

Vice President Pence vowed Saturday that Gorsuch would be confirmed “one way or another.”

Here is the full lineup:
