A high school in Littlestown, Pa., has apologized after the yearbook club blurred out two teenagers’ pro-Trump apparel in a yearbook photo.

“The mistake was not noticed during the editorial preview process prior to print. We apologize on behalf of the yearbook club. It is not the policy or practice of the district to improperly censor speech,” Littlestown High School said in a statement to local Fox News affiliate WPMT.

The apology comes after 16-year-old Jeremy Gebhart said he and his friend had their “Make America Great Again” hats blurred out of a yearbook photo taken during the school’s spirit week.
