A Holocaust Remembrance Day event in Arkansas city, Arkansas was interrupted by a group of white supremacists, a local news station reported.

About 8-12 men strolled by the Holocaust Remembrance event holding swastika flags, a white cross and posters with anti-Semitic slogans.

The appearance of the white supremacist group comes as Arkansas Technical University, located in Russellville, is being criticized for creating a scholarship in honor of a deceased professor who many have taught Holocaust-denying books in his class.

But in a letter sent to the school last week, the ADL alleges that Link consistently gave students books that questioned the “myth” of the Holocaust, and participated in online forums where he denied the historical reality of the Holocaust. The university has said that it has no evidence that Link was a Holocaust denier, but appears to have elided evidence that others had raised concerns about Link’s beliefs about the Holocaust more than ten years ago.

People present at the event this week posted pictures of the white supremacists, many of whom wore camouflage-print clothing and masks and hats that obscured their faces.

Russellville is something of a hot spot for white supremacists. In February, authorities arrested 54 members of a white supremacist gang in and around Russellville. The group, called the New Aryan Empire, has been fingered for murders, violent assaults, kidnappings and meth distribution in the area.
