Students at a northern Texas high school toted “Trump/Pence” signs and chanted “Build that Wall” during a volleyball game against a school located on the west Texas-Mexico border, officials said Sunday.

Students from Archer City ISD broke out in the chant during a match against Fort Hancock ISD on Nov. 11. A photo from the match posted to Facebook shows several students dressed up in wigs while displaying a Donald Trump campaign sign.

“The fans started chanting BUILD THAT WALL directing at the (Fort Hancock) team and followers,” Carlos Urias, who posted the photo, said in a caption. “No doubt in my mind that this sentiment has always existed with groups of people but to display it so openly is so not correct!”

The chant became a regular occurrence while the President-elect was campaigning and references his promise to build a wall along the southern border once he takes office.

Archer City district officials acknowledged the “offensive language” in a Sunday Facebook post and vowed to take “appropriate action” against the students involved.

“In no way do we condone this type of language or behavior,” the post stated. “We apologize to the students and community of Ft. Hancock. The administration is making every effort to ensure this doesn’t happen again.” Officials did not immediately return a request for comment on how the school would prevent similar incidents from occurring in the future.
