WATCH: Space Force Commander speaks out after being fired for warning against Marxism and Critical Race Theory in the military

"Let me give you one example of what I saw in the past 10 months when I was in command of a unit," Lohmeier said.

"I began noticing some time ago and not just in the past few months, but over the past several years, an increasing relevance of what I saw was a Marxist ideology parading around by other names," Lt. Col. Lohmeier said.

The secretary of the Department of Defense called for an extremism down day and issued a guidance memorandum to all service members in February.

"In the guidance memorandum, he basically gave an injunction to every service member to combat extremist ideologies within the force where they saw them…and to take it upon ourselves, to protect one another, and to speak up and educate one another about extremist ideologies when we discovered them causing divisions within the force," explained Lt. Col. Lohemier, author of Irresistible Revolution.

Fox News' host Sean Hannity went on to slam the US military for teaching that the Constitution ratified the US and codified white supremacy as the law of the land, which was mentioned in Lohmeier's book Irresistible Revolution.

Hannity asked Lohmeier if the United States military recognizes the incredible strides the US has taken to form a more perfect union such as the Civil War and the Civil Rights Acts.

"I think it is recognized," Lohmeier said.

"And I think one of the things that the defense department does very well is make it very clear that we've got zero tolerance for discrimination of any kind based on race, sex, politics, religion," Lohmeier continued.

However, Lohmeier made it exceedingly clear that during his time as Commander he had a zero tolerance policy for political discrimination, as well.

"I've made that very clear to my own people that in the light of a hyper politicized environment that I've seen since taking command, and I'm no longer in command, I will not tolerate any discrimination of any kind based on politics, for example," Lohmeier expressed to Hannity.

"There were videos being sent out to every base, service member, that we were asked to watch in preparation for our extremism down days and discussions on race in which we were taught that the country was evil, that it was founded in 1619 and not 1776, and that whites are inherently evil," Lohmeier explained.
