Rolling Stone magazine published a story on March 14 about campaign advertising for former President Donald Trump being featured before videos calling Adolf Hitler a hero.

The ad appeared on Rumble—a video-streaming platform akin to YouTube with looser moderation standards—prior to showing content by Stew Peters, a pro-Hitler conspiracy theorist who has featured neo-Nazi podcaster Nick Fuentes on his eponymous program, “The Stew Peters Show.”

One video with Peters narrating describes Nazi Germany as needing to storm “perverted libraries” and “perverted bookstores,” featuring black-and-white antisemitic political cartoons while asking, “Why do Jews push pornography & degeneracy on our children?”

Peters has also defended the Holocaust, saying that Jews had pushed Nazis “to their breaking point.”

Rumble, also a web-hosting and cloud services business, is based in Toronto, Canada, with its U.S. headquarters in Florida.

The Trump campaign blamed Rumble, releasing a statement saying it was not “picking any particular video or channel to run ads on, and we are not given visibility into every single ad that is served during every video. Rumble is ultimately responsible for the ads that are served on any given video on their platform.”

JNS contacted the Trump campaign asking if it would discontinue ad buys on Rumble and has not received a response.
