(JTA) — Quarterback Brett Favre and other celebrities were duped by a group of white supremacists into making videos that included coded anti-Semitic messages.

The group behind the videos calls itself the GDL, or Goyim Defense League, using the Hebrew word for a non-Jew, BuzzFeed News first reported. It is a play on the ADL, or Anti-Defamation League, a Jewish defense organization.

The videos were made using Cameo, where users can pay to have celebrities record a personalized message for them. Cameo has become a platform used by the far-right to legitimize hate messages, according to BuzzFeed.

Favre, actor Andy Dick and rapper Soulja Boy recorded messages at the request of the “GDL,” according to reports.

Favre makes $500 for each Cameo video, and has recorded more than 50 since it went online in April 2018. The person booking the Cameo submits instructions with what the celebrity is supposed to say.

BuzzFeed published the text of the message but not the video so as not to allow it to go viral.

“Brett Favre here with a shoutout to the Handsome Truth and the GDL boys,” Favre said in the video. “You guys are patriots in my eyes. So keep waking them up and don’t let the small get you down. Keep fighting too and don’t ever forget the USS Liberty and the men and women who died on that day. God bless and take care,” the 30-second message said.

The small refers to small hats, which is a slur for yarmulke. The USS Liberty is a U.S. vessel that was fired upon by Israeli forces during the Six-Day War in 1967 that Israel mistook for an Egyptian ship.

Favre said in a post on Facebook that he thought he was making a video in support of U.S. troops.

“Since I match service dogs with military veterans who have PTSD, I assumed that the request stemmed from my interest in veterans affairs and recorded the message,” he wrote.

“A few days later, I was distressed to learn that the request came from an anti-Semitic group that reposted my video with comments implying that I endorsed their mission. Nothing could be further from the truth.”

Favre said he donated his fee to charities fighting against hate and bigotry.

The video has been removed by Cameo, but copies remain on anti-Semitic message boards, according to BuzzFeed.
