Fox News host Greg Gutfeld raged at a colleague on Monday's episode of "The Five" after she mentioned an example of political violence committed by a right-wing extremist.

Gutfeld and left-leaning co-host Jessica Tarlov got into a debate about whether more information is needed to understand the motives of conservative activist Charlie Kirk's murderer. President Donald Trump blamed "radical left lunatics" for Kirk's killing, a line that the right-wing media have repeated incessantly.

Gutfeld argued that no more information is needed, which surprised Tarlov.

"Why is this only happening on the left and not the right?" Gutfeld asked, referring to Kirk's politically motivated murder. "That's all we need to know!"

"Oh really?" Tarlov replied. "What about Vance Boelter? What about Melissa Hortman?"

Boelter, 57, of Minnesota, was indicted on federal charges of stalking and murdering Hortman, the state's former Democratic House Speaker, and her husband, Mark, over the summer.

Boelter also shot Minnesota State Senator John Hoffman, a Democrat, and his wife, Yvette, according to a press release.

"Did you know her name before she was killed?" Gutfeld replied. "Did any of us spend every single day talking about Mrs. Hortman? I never heard of her until after she died."

"So she doesn't matter?" Tarlov replied.

"The fact of the matter is, the both-sides argument not only doesn't fly, but we don't care!" Gutfeld responded.
