Sen. Lindsey Graham, who could become Senate Judiciary chairman next year, warned his Democratic colleagues Friday that he will remember how they handled the Brett Kavanaugh saga.

“If I am chairman, next year, I’m going to remember this,” the South Carolina Republican said before a planned vote on the Supreme Court nominee.

“There’s the process before Kavanaugh and the process after Kavanaugh. If you want to vet the nominee, you can. If you want to delay things until after the election, you cannot. If you try to destroy somebody, you will not get away with it.”

On Thursday, Graham castigated Democrats for how unfairly he said they had treated the nominee.

The senator was the first Republican to question Kavanaugh after outside counsel Rachel Mitchell had questioned accuser Christine Blasey Ford and Kavanaugh.

He asked the nominee if Judiciary ranking member Dianne Feinstein had asked him about the Ford allegation during a private meeting in August; Kavanaugh replied no.

“This is the most unethical sham since I’ve been in politics,” Graham yelled.

“God, y’all want power and I hope you never get it,” an angry Graham said to the Democrats.

Then he addressed Kavanaugh: “These have been my friends, but when it comes to this, if you’re looking for a fair process, you came to the wrong town at the wrong time.”

Pointing his finger for emphasis, Graham then sent a message to his GOP colleagues, some of whom might be on the fence on the nomination: “If you vote no, you’re legitimizing the most despicable thing I have seen in my time in politics.”
