GENEVA – A parent disrupted the Pledge of Allegiance at Mill Creek Elementary School on Wednesday afternoon, prompting district officials to increase security measures and send a letter home to parents.

According to a statement from Geneva School District 304, a parent used “language that is not typically heard in a school setting” while a kindergarten class was present in the school’s library. The statement says that the situation was resolved quickly, and the Kane County Sheriff’s Office was notified.

The parent, Colin McGroarty, 41, whose children attend Mill Creek, said he was at the school earlier than usual Wednesday and saw students saying the Pledge of Allegiance. He said he volunteers at the school for a few hours around noon every Wednesday.
