Senate Majority Leader Mitch McConnell (R-Ky.) slammed Democrats holding up the latest of President Trump's cabinet appointments up for committee votes.

"It is time to get over the fact that they lost the election," he told The Hill.

Earlier Tuesday, Ohio Sen. Sherrod Brown organized a party-line boycott of the Senate Finance Committee's vote on treasury secretary nominee Steven Mnuchin.

A Finance Committee vote on Rep. Tom Price's (R-Ga.) nomination to be secretary of health and human services was also boycotted by Democrats.

Additionally, Sen. Jeff Merkley (D-Ore.) said he would filibuster Trump's Supreme Court nominee if it wasn't Merrick Garland, who former President Barack Obama had nominated last year.

Appearing on "Special Report" after Neil Gorsuch was nominated to the Supreme Court, McConnell said he's "encouraged" by the initial reactions of Democrats. 

He cautioned that a filibuster of Gorsuch's nomination would not be a good idea and dismissed Democrats who've compared the situation to President Obama's nomination last year of Merrick Garland. 

The Senate refused to bring Garland's nomination up for a vote, preferring to wait until the election was over.

McConnell said a vacancy in the middle of an election year "has nothing whatsoever to do with" a new president nominating a justice.

"The Senate has not confirmed a vacancy in the middle of a presidential election year in 80 years. ... If the shoe had been on the other foot, they wouldn't have filled the vacancy," he said.
