In 2017, the chapter at Indiana University was shut down following an investigation which found that chapter members were "involved in activities that do not represent our high standards or align with Tri Delta's purpose." Chapter members also "violated the chapter's previous probation terms." The national organization declined to specify further, but noted that the chapter had "been on probation for three consecutive semesters, and each time was asked to take responsibility for their actions. Each time ... the chapter chose to ignore advice and recommendations, sending a strong message that they had no intention of making positive change."
