CBS News host Margaret Brennan faced backlash over the weekend after interviewing Secretary of State Marco Rubio and stating that Nazi Germany "weaponized free speech" to conduct the Holocaust. 

Rubio and Brennan exchanged a back and forth about Vice President J.D. Vance's speech in Munich where he criticized European countries for censorship of their citizens. 

"Well, he was standing in a country where free speech was weaponized to conduct a genocide," Brennan said, referencing Vance. "He met with the head of a political party that has far-right views and some historic ties to extreme groups. The context of that was changing the tone of it. And you know that."

Rubio shot back at Brennan, saying that he disagreed with her and that there was no free speech or opposition in Nazi Germany. 

"Free speech was not used to conduct a genocide," he said. "The genocide was conducted by an authoritarian Nazi regime that happened to also be genocidal because they hated Jews and they hated minorities, and they had a list of people they hated, but primarily the Jews."

This resulted in multiple conservatives criticizing Brennan's take, including Vance.

"This is a crazy exchange," the vice president wrote on the social media platform, X. "Does the media really think the holocaust was caused by free speech?"

"This is the first time I’ve heard the theory that the Holocaust wasn’t conducted with gas chambers but with free speech zones," another user wrote.

The show "60 Minutes" on CBS News recently conducted an interview with German prosecutors who explained that hate speech is illegal in the country, but free speech is still present.

Dr. Matthaus Fink, one of the state prosecutors interviewed, said that free speech is legal, but it has limits.

"Insulting someone is not a crime, and criminalizing speech is going to put real strain on European-US relationships," Vance said in response to the interview. "This is Orwellian, and everyone in Europe and the US must reject this lunacy."
