Gregory Salcido, the California high school teacher that drew national headlines for calling U.S. military members “dumb sh*ts” and the “lowest of the low,” was terminated from his teaching position via unanimous school board decision in March. Now, the details of the board’s investigation into his behavior in the classroom have revealed a history of unprofessional and inappropriate behavior that extend well beyond his controversial views on the military.

“Your freakin’ stupid Uncle Louie or whatever. They’re dumb***ts. They’re not high-level thinkers. They’re not academic people. They’re not intellectual people … They’re the freaking lowest of our low.” Salcido said in an anti-military rant the was prompted by one of his students wearing a Marine Corps sweatshirt to class. He went on to say that people choose to serve in the military because “you didn’t take care of business academically, because your parents didn’t love you enough to push you and then you didn’t love yourself enough to push yourself.”

One of the students secretly recorded the tirade and uploaded the footage online, drawing a negative reaction from service members and veterans all over the country. Even White House Chief of Staff, retired Marine General John Kelly chimed in.

“Well, I think the guy ought to go to hell,” Kelly said at the time. “I just hope he enjoys the liberties and the lifestyles that we fought for.”
