Officials at the Auschwitz-Birkenau Memorial and Museum on Tuesday criticized Rep. Clay Higgins, R-La., for a video he filmed inside a gas chamber at the former Nazi concentration camp in Poland.

On Saturday, Higgins released the video of him inside a former gas chamber at the museum in Oswiecim, Poland. In the video, Higgins said the gas chamber killings took only about 20 minutes and show why the U.S. military “must be invincible.”

Higgins, who has been dubbed the “Cajun John Wayne,” also said in the video: "The world's a smaller place now than it was in World War II. The United States is more accessible to terror like this, horror like this. It's hard to walk away from the gas chambers and 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."

On Tuesday, the museum tweeted: “Everyone has the right to personal reflections. However, inside a former gas chamber, there should be mournful silence. It’s not a stage.”

The tweet also had a link to an article that contained Higgins’ five-minute video, titled a “message for America.”
