The emergence of a neo-Nazi group at Colorado State University has prompted the school to beef up security for a conservative speaker invited to the Fort Collins campus by a different group.

CSU President Tony Frank said the university is not linking Turning Point USA founder Charlie Kirk with the Traditional Worker Party, a white nationalist group that promotes segregating the races.

But several fliers attributed to the TWP have been posted on campus and that the group has been attempting to actively recruit on college campuses across the country, he wrote in a letter to students, faculty and staff on Thursday.

The recent appearance of white nationalist rhetoric on campus has been “conflated” with Kirk’s planned speech in the Lory Student Center Friday evening and raised concerns about the safety of religious groups, people of color, and other populations possibly targeted by protesters and counter-protesters on Friday, Frank wrote.

Turning Point USA has no track record of causing disturbances on college campuses, he said. Officials with Turning Point USA weren’t immediately available for comment Thursday.

“But let me keep this simple: a Nazi is a Nazi is a Nazi,” Frank wrote, noting that TWP goes by various names online. “And the members of the Traditionalist Worker Party are unapologetic Nazis who advocate murdering all those who don’t align with their worldview.”

The Southern Poverty Law Center, which tracks hate groups in the United States, says that even though the TWP claims to oppose racism, it is “intimately aligned with neo-Nazis and other hard-line groups.”

Kirk’s group, which promotes conservative policies including limited government and free markets, was invited by a group of students to talk about his opposition to socialism. The students followed all the proper steps to bring Kirk to CSU, Frank wrote.

CSU has a security plan in place for Kirk’s talk, Frank wrote. “Our priority will be to protect the public safety while also allowing people to exercise their constitutional rights to peaceful protest and assembly.”
