Rubio attended the Munich Security Conference with Vance this weekend, which was Vance’s first foreign trip since taking office as vice president. In his first international address, Vance assured other leaders that “under Donald Trump’s leadership, we may disagree with your views, but we will fight to defend your right to offer it in the public square, agree, or disagree.” During a segment on CBS News’s Face the Nation Sunday, Rubio faced questions about the speech.

“[Vance] also met with the leader of a far-right party known as the [Alternative for Germany], which, as you know, is under investigation and monitoring by German intelligence because of extremism. What did all of this accomplish other than irritating our allies?” host Margaret Brennan asked.

“Why would our allies or anybody be irritated by free speech and by someone giving their opinion?” Rubio posed his own question in response. “He simply expressed in a speech his view of it, which a lot of people frankly share, and I thought he said a lot of things in that speech that needed to be said. And honestly, I don’t know why anybody would be upset about it.”

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

“No, I have to disagree with you. Free speech was not used to conduct a genocide. 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 hated those that they had a list of people they hated, but primarily the Jews,” Rubio said. “There was no free speech in Nazi Germany. There was none. There was also no opposition in Nazi Germany. They were a sole and only party that governed that country. So, that’s not an accurate reflection of history.”

The objective of the Munich Security Conference, according to its website, is “to build trust and to contribute to the peaceful resolution of conflicts by sustaining a continuous, curated and informal dialogue within the international security community.”

Alternative for Germany, the right-wing party in the country, is fresh from earning second place with nearly a fifth of the vote during its election last year. It condemns abortion and multiculturalism. Chancellor Olaf Scholz’s Social Democratic Party earned its worst result ever.
