Controversy
In 2011, Trinity was the subject of a police investigation after an open lewdness incident was reported at the football team's training camp. A number of Trinity students who were identified as the perpetrators of the event were subsequently prosecuted. The school also disciplined students, which included expulsion for some.
The Trinity football program came under media and police scrutiny for off-season misconduct in 2016 when two team members were captured on video assaulting a man while attending a Donald Trump rally at neighboring Cumberland Valley High School. These students faced consequences from the school, including cleaning it.
