According to Donald Trump’s spokesperson, the phrase “bringing a knife to a gun fight” incites violence, even though CNN’s Jake Tapper tried to inform her otherwise.

Katrina Pierson’s comment came on Monday while being questioned by Tapper about a comment Trump made where he said that “like, basically none” have been hurt at his rallies.

“If we want to talk about inciting violence, where is the interview with Hillary Clinton and (President) Barack Obama when they’re talking about ‘bringing a gun to a knife fight?’” Pierson said. “They’re inciting violence against police officers.”

It was during the 2008 presidential campaign that Obama used the phrase.

“If they bring a knife to the fight, we bring a gun,” Obama said of fighting back against political attacks from Republicans during the race against Arizona Sen. John McCain.

Tapper tried to fill Pierson in on the phrase from the 1987 mobster movie “The Untouchables.” To “bring a knife to a gun fight” means being unprepared for a situation.

“I didn’t recognize that, absolutely not,” Pierson said when Tapper referenced the phrase.

“Well, you should check out the film ‘The Untouchables,’” Tapper said.

Monday’s appearance wasn’t the first time Pierson has had an odd interview on CNN.

In December, she debated the meaning of “schlonged” after Trump said Hillary Clinton “got schlonged” by Barack Obama in 2008.

She also once wore a bullet necklace on CNN and after catching some criticism on social media, said “maybe I’ll wear a fetus next time.”
