(CNN) Republican Sen. Lindsey Graham said at an event Wednesday he didn't like President Donald Trump's mockery of Christine Blasey Ford at a rally Tuesday night, adding that the South Carolina Republican "would tell him to knock it off."

"Sometimes people are accused of something they didn't do," Graham said Wednesday at the "Atlantic Festival," in Washington. "So President Trump went through a factual rendition, that I didn't particularly like, and I would tell him to knock it off. You're not helping. But it can be worse, you can actually kill somebody's cat, and puncture their tires to get them to shut up."

Graham, an ardent supporter of Supreme Court nominee Brett Kavanaugh, has been one of the Senate Judiciary Committee's fiercest proclaimers of his innocent against Ford's sexual assault allegations.

The Atlantic's Jeffery Goldberg asked Graham about Trump's remarks, calling them "a personal, degrading attack on someone who is a private citizen." Defending the President, Graham retorted "You know, here's what's personally degrading: 'this is what you get when you go through a trailer park with a $100 bill.'"

The Senate Judiciary member quoted a remark by James Carville, a strategist for President Bill Clinton. Carville said "if you drag a $100 dollar bill through a trailer park, you'll never know what you'll find," after Paula Jones accused Clinton of sexually harassing her in 1991.
