Sen. Chuck Grassley, R-Iowa, said in an interview that aired Tuesday night that he would not take up another Supreme Court nomination should it come up in the 2020 election year.

“If I'm chairman, they won't take it up, no,” Grassley said when asked if the Senate Judiciary Committee would consider another Trump Supreme Court nomination in 2020. “Now if someone else is chairman of the [Judiciary] Committee, they’ll have to decide for themselves. But that's a decision I made a long time ago.”

Grassley said that he made a pledge in 2016, when former President Obama’s Supreme Court nominee Merrick Garland was blocked by a majority Republican Congress, to not consider Supreme Court nominees in presidential election cycles.

The Senate Judiciary Chairman’s decision directly contradicts a statement from Senate Majority Leader Mitch McConnell, R-Ky., made over the weekend, when he suggested that he was prepared for another Trump Supreme Court pick in 2020.

“We’ll see if there is a vacancy in 2020,” McConnell said Sunday.

McConnell claimed that blocking Garland in 2016 was appropriate because it was following a Senate precedent from 1880 that justified blocking a nominee in the situation where the Senate was controlled by the party opposing the sitting president.

However, he indicated that going through with a nomination in the 2020 election year would be appropriate if the Congress remained a GOP majority.

This post has been updated to reflect that Grassley's comments pertained to 2020, not the 2020 election cycle.
