A Philadelphia high school teacher is under investigation after she reportedly ordered a student to take off a t-shirt supporting Mitt Romney’s presidential campaign and compared the shirt to a Ku Klux Klan sheet.

The incident occurred at Charles Carroll High School in Port Richmond. When the student refused the order, she tried to throw the girl out of class.

The teacher reportedly told the 16-year-old student that the high school was a “Democratic school” and then threatened to use a marker to cross out Romney’s name.
