Teachers mock high school student’s ‘Make America Great Again’ hat

Three weeks ago at South Portland High School in Maine, student Connor Mullen began wearing a hat with the popular Donald Trump campaign slogan “Make America Great Again” emblazoned on it.

He concedes that he expected to be razzed for it by his peers (and he was) — but not by school officials.

Allegedly, a teacher told Mullen “Thank God you can’t vote,” and an “education technician” mocked him as an “uninformed voter” … to the laughter of his classmates.
