South Dakota political leaders are condemning Nazi demonstrations that happened Saturday in Deadwood and on the Capitol grounds in Pierre.

The state Department of Public Safety said in a news release that a group attempted an unscheduled protest on the Capitol grounds, without a permit. The Highway Patrol asked the group to leave and the march “ended without incident,” according to the news release.

Images and video circulated online of about a dozen people dressed in red and black, with black masks covering their faces, carrying a Nazi flag and unfurling it on the steps of the Capitol. Images also surfaced of a similar march in Deadwood.

On her personal X (formerly Twitter) account, Gov. Kristi Noem wrote, “Nazis are not welcome here in South Dakota.”

“We stand for life, liberty, and the pursuit of happiness,” she wrote. “We reject all hatred and Nazis.”

A known neo-Nazi leader, Christopher Pohlhaus, appeared to claim responsibility for the march when he shared Noem’s post on his own X account and said “we occupied your steps for the entire time we intended to be there.” According to the Anti-Defamation League, Pohlhaus is a former Marine turned tattoo artist and leader of the neo-Nazi “Blood Tribe.”

Other South Dakota political leaders also condemned the marches. U.S. Sen. Mike Rounds tweeted, “This is disgusting. This racist behavior has no place in South Dakota or anywhere.” U.S. Rep. Dusty Johnson tweeted of the incident, “This is atrocious.”

The activity is part of a resurgence of in-person demonstrations among white nationalist, neo-Nazi and far-right reactionary groups throughout the country, according to the Southern Poverty Law Center’s latest annual report on hate and extremism.

“For the first time since 2018, these racist activists, who together make up what is known as the white power movement, turned out in droves, holding 191 demonstrations in 2022 and 143 in 2023,” the report says.
