That ad is one of the dumbest attempts at damage control I think I've ever seen.
He spends more time on a soap box ranting about COVID-19 and masks then actually addressing what he's actually in hot water about. It's literally just "The student violated dress code standards and I'm totally not a racist, BUT LET ME TELL YOU ABOUT THE TYRANNICAL GOVERNMENT MAKING WEAR MASKS OVER THE COVID HOAX!!!!!!!!"
