Two Ladue Horton Watkins High School students were disciplined last week after one student suggested that black students should go to the back of the bus.

The incident happened on Thursday afternoon, when two male students were boarding a school bus that was fairly full.

They were chanting, “Trump, Trump, Trump,” said Susan Downing, spokeswoman for the school district.

The chanting escalated to the point where one of the students suggested that African-American students should sit in the back of the bus.

“That clearly upset people on the bus,” Downing said.

The next morning, school officials interviewed the students involved and reviewed school bus tapes of the incident. The two boys were disciplined.

The district cannot say who the students are or how they were disciplined because of federal student privacy laws. But Downing said that in situations like this, suspension “would not be an unusual punishment.”

“This is not something we are taking lightly at all,” she said. “This is not what we stand for in our district and it's time to react to that and make sure that we know who we are, what's expected and what we stand for as a school community."
