The Auschwitz Memorial on Tuesday condemned a video posted over the weekend that shows U.S. Rep. Clay Higgins inside a former gas chamber at the concentration camp, speaking to the camera.

“Everyone has the right to personal reflections. However, inside a former gas chamber, there should be mournful silence,” the Auschwitz Memorial tweeted from its official account. “It’s not a stage.”

In the video, posted on YouTube by Lee Johnson Media, Higgins appears to walk through different areas at Auschwitz, a Nazi concentration camp in Poland. He shows viewers one of the four gas chambers at the camp and explains how the killings took only about 20 minutes.

"This is why Homeland Security must be squared away, why our military must be invincible," Higgins said in the video.

Later, he stands outside and delivers a sober speech to the camera about the “evils of the world.”

“The world’s a smaller place now than it was in World War II,” Higgins said. “The United States is more accessible to terror like this, horror like this. It’s hard to walk away from gas chambers, ovens without a very sober feeling of commitment, unwavering commitment, to make damn sure that the United States of America is protected from the evils of the world.”

Higgins shared the video on one of his two Facebook pages, calling it "a stark reminder about the Independence we celebrate on July 4."

The Louisiana congressman recently came under fire for controversial comments he made in a Facebook post after a deadly terror attack in London last month, calling for "every conceivable measure" to be used to hunt down and kill anyone suspected of being an Islamic radical.
