Santa Ana High School Principal Jeff Bishop said in a Facebook post on Saturday that fans from Aliso Niguel High School held signs that featured messages such as “Build The Wall,” a reference to President Trump’s oft-used promise in his 2016 presidential campaign.

Santa Ana High School has a predominantly Hispanic student body, while the majority of Aliso Niguel’s students are white, according to The Orange County Register.

Bishop told the Register that he did not see the complete wording of the signs at the game, but he said he saw something about Trump.

Deni Christensen, principal at Aliso Niguel, told the newspaper that she had multiple politically charged signs removed from the event.

In addition to the posters, Bishop said he was angered by Aliso Niguel’s chants of “USA” after it scored touchdowns. Bishop added that he told Christensen at halftime that if the chants continued, the team would walk of the field.

“I told her ‘You’re playing Americans. You’re playing ‘Dreamers,’ ” Bishop said. ” ‘I don’t understand the USA pride thing when you score. And if I hear it one more time, I am walking off the field with the team.’ ”
