Rudy Giuliani’s assertion that “truth isn’t truth” topped a Yale Law School librarian’s list for the most notable quotes of 2018, according to The Associated Press.

The statement went viral in August after Giuliani, a personal attorney for President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

In response to moderator Chuck Todd's statement that “truth is truth,” Giuliani responded: “No, it isn’t truth. Truth isn’t truth.”

Giuliani said he was trying to make the point that an interview would be fruitless since Mueller and Trump were in disagreement over fundamental aspects of the special counsel’s inquiry.

"We have a credibility gap between the two of them," Giuliani went on to say. "You’ve got to select one or the other."

Giuliani’s quote is one of several on the list related to the president, including Trump’s January tweeted declaring himself a “stable genius.”

The list also featured several other political quotes, including Supreme Court Justice Brett Kavanaugh Brett Michael KavanaughHarris faces pivotal moment with Supreme Court battle Poll: 59 percent think president elected in November should name next Supreme Court justice Feinstein 'surprised and taken aback' by suggestion she's not up for Supreme Court fight MORE's comments about beer during his confirmation hearing, Meghan McCain's eulogy for her father and more.

“I liked beer. I still like beer," which was said by Kavanaugh during his confirmation hearing, is second on the list.

Kanye West's remark about the "dragon energy" he and Trump share also made the list.

“You don’t have to agree with Trump but the mob can’t make me not love him. We are both dragon energy. He is my brother. I love everyone," West said in April.

That quote resulted in a strong backlash among liberals against the famed rapper and began a months-long controversy regarding the musician's relationship with the president.

The Yale list was first established in 2006 and is updated yearly with quotes that are famous or are believed to represent the times.
