Jewish news publication The Forward reported that Trump administration official Sebastian Gorka is a “formal member” of the Vitézi Rend, a far-right nationalist Hungarian group that, according to the State Department, operated under the direction of Nazi Germany during World War II. Gorka, a top counterterrorism adviser to President Donald Trump and former national security editor for “alt right” website Breitbart.com, denied that he was a member of the group when contacted by another publication.

The Forward spoke to two leaders of the Vitézi Rend, Gyula Soltész and Kornél Pintér, who said Gorka is a sworn member of their organization. From the March 16 article:

Gorka, who pledged his loyalty to the United States when he took American citizenship in 2012, is himself a sworn member of the Vitézi Rend, according to both Gyula Soltész -- a high-ranking member of the Vitézi Rend’s central apparatus -- and Kornél Pintér -- a leader of the Vitézi Rend in Western Hungary who befriended Gorka’s father through their activities in the Vitézi Rend.

Soltész, who holds a national-level leadership position at the Vitézi Rend, confirmed to the Forward in a phone conversation that Gorka is a full member of the organization.

“Of course he was sworn in,” Pintér said, in a phone interview. “I met with him in Sopron [a city near Hungary’s border with Austria]. His father introduced him.”

The Forward explained that the Vitézi Rend “is listed by the State Department as one of many groups in Germany and the countries it occupied as collaborationist ‘criminal organizations’ with the Nazis as determined by the post-war International Military Tribunal at Nuremberg.” Soltész also told BuzzFeed that Gorka is a current member of the Vitézi Rend. Gorka denied these ties to Tablet magazine, telling a reporter, “I have never been a member of the Vitez Rend. I have never taken an oath of loyalty to the Vitez Rend. Since childhood, I have occasionally worn my father’s medal and used the ‘v.’ initial to honor his struggle against totalitarianism.” (Foward’s article described how Gorka has signed testimony submitted to Congress and other documents with a “v.,” which “is an initial used by members of the Vitézi Rend” after they have taken a sworn oath.)

Tablet added that Gorka’s father was “a dedicated member of the anti-Communist underground, and had risked his life to organize the Hungarian resistance and deliver vital information about the Soviets to western intelligence agencies, including the MI6. He was eventually arrested, badly tortured, spent two years in solitary confinement and some more in forced labor in the coal mines before eventually escaping to England.”

Back in February, foreign policy blog LobeLog confirmed with an expert that a medal Gorka had worn to an inaugural ball was from the Vitézi Rend. Breitbart.com editor Joel Pollak defended Gorka in a February 14 article, calling claims about his connections to the Vitézi Rend a “smear” and defending the group by calling it “anti-communist.”

USA Today reported that following Forward’s report, Steven Goldstein, executive director of the Anne Frank Center for Mutual Respect, said in a statement that “Sebastian Gorka must resign -- and President Trump must make it happen,” and that the National Jewish Democratic Council also urged Trump to fire Gorka. BuzzFeed quoted Rep. Jerrold Nadler (D-NY) calling the reports “deeply disturbing” and saying: “It’s shocking that with these revelations he’s not already fired by the president.” Representatives of the Council on American-Islamic Relations, Muslim Advocates, the Muslim Public Affairs Council, and the Southern Poverty Law Center also told BuzzFeed that Gorka should resign or that Trump should fire him if the reports about his membership are further substantiated.

A reporter for Talking Points Memo later tweeted a statement from the Anti-Defamation League, which stated “If true, [Gorka] needs to renounce his membership immediately and disavow their exclusionary message of hate. At a time of rising anti-Semitism around the world, it is essential for Mr. Gorka to make clear that he rejects the policies of far-right and nativist organizations such as Vitézi Rend and Jobbik, which have a long history of stoking anti-Semitism and intolerance in Hungary.”

Before he was hired by the Trump administration, Gorka worked for Breitbart.com as a national security editor and was a paid adviser to the Trump campaign. In the past he has used anti-Muslim rhetoric and backed conspiracy theories. For example, after the Washington National Cathedral hosted an event with two Muslim groups in 2014, Gorka wrote an article for Breitbart.com with the headline “Muslim Brotherhood Overruns National Cathedral In DC," arguing that “if a place of worship is used by Muslims for their prayers, that territory subsequently becomes part of Dar al Islam, sacred muslim (sic) land. Forever.” Gorka also defended Trump’s false campaign claim that former President Barack Obama was the “founder of ISIS,” saying he “is absolutely right” if he meant the Obama administration “facilitated the growth of ISIS.”
