Republican Clay Higgins said in the video that the horrors of the World War-2 death camps were the reason why the U.S. military should be "invincible".
"Everyone has the right to personal reflections", the post said. It's not a stage.
Officials from the Auschwitz-Birkenau Memorial and Museum in Poland were not amused at the video, which Higgins posted on Saturday.
As President Trump visits Poland Wednesday, a US congressman is stirring up controversy with a video recorded at the Auschwitz-Birkenau Memorial and Museum.
Auschwitz was a collection of Nazi concentration and extermination camps constructed in the lead-up to World War II created to detain and, later, kill some 960,000 of the 1,095,000 Jewish people that were deported there, along with another 100,000 other people who weren't Jewish but deemed "undesirable" (Poles, gypsies, queer people, Soviet prisoners of war, people living with mental illness; the list goes on).
Higgins made news last month after a terror attack in London when he posted on Facebook the assertion that "the free world ... all of Christendom ... is at war with Islamic horror".
In the video, Higgins walks through the property and explains why he thinks it's important to remember those who died in the chambers. It requests "silence", and a "respect" for the memory of the thousands of people killed by the Nazi SS.
A US CONGRESSMAN has come under fire for sending a "message to America" from inside the Auschwitz Memorial.
On Wednesday, the Anne Frank Center tweeted about the video, calling it disgusting and suggesting Higgins apologize, get sensitivity training, "or get a new job".
Higgins' video also prompted an outcry from Twitter users, some of whom were from the congressman's home state.
