Hilliard Davidson High School senior Jacob Shoemaker was then reportedly slapped with a suspension.
The student argued that divisive politics have no place in America's schools and he refused to take sides in the debate, according to the Associated Press.
Shoemaker's suspension citation was posted online, possibly by a friend, and the story quickly went viral.
"Student refused to follow instructions after being warned repeatedly by several administrators," the letter said. "Student not permitted on school property."
School district spokesperson Stacie Raterman said official policy prohibited school officials from leaving Shoemaker unattended in the building for "security reasons," 10TV reported.
