"The same EU globalist scum are trying to bully ?@elonmusk? in to censorship with criminal prosecution threats. Now they are moving in on Tucker! We must stand together for free speech," wrote Infowars founder Alex Jones on social media.

Newsweek was told by former Belgian Prime Minister and current member of the European Parliament Guy Verhofstadt that Carlson should be banned from entering EU nations because he's "a mouthpiece" of Putin and U.S. presidential frontrunner Donald Trump.

"Putin is a war criminal and the EU sanctions all who assist him in that effort, it seems logical that the External Action Service examine his case as well," Verhofstadt said.

Former MEP Luis Garicano told the outlet Carlson "is no longer a newsman, but a propagandist for the most heinous regime on European soil and the one which is most dangerous to our peace and security."

MEP Urmas Paet said, "Carlson wants to give a platform to someone accused of crimes of genocide—this is wrong. If Putin has something to say he needs to say it in front of the ICC. At the same time Carlson is not being a real journalist since he has clearly expressed his sympathy for the Russian regime and Putin and has constantly disparaged Ukraine, the victim of Russian aggression."
