Washington, DC (CNN)A Space Force lieutenant colonel has been removed from his command after appearing on a conservative podcast criticizing the United States military.

Lt. Col. Matthew Lohmeier joined The Steve Gruber show to discuss his new book, "Irresistible Revolution: Marxism's Goal of Conquest & the Unmaking of the American Military," which alleges that Marxist ideologies are becoming widespread within the armed forces. He expounded on those concerns in the podcast.

"Since taking command as a commander about 10 months ago, I saw what I consider fundamentally incompatible and competing narratives of what America was, is and should be," Lohmeier said. "That wasn't just prolific in social media, or throughout the country during this past year, but it was spreading throughout the United States military.
