While their on-screen relationship was darling on “Chicago P.D.”, it seems that wasn't the case in real life for Sophia Bush and Jason Beghe. In 2017, Variety reported that Bush's departure from the show at the end of its fourth season was partly due to verbal abuse from co-star Beghe.
NBC launched an investigation in 2016 after receiving "multiple complaints about Beghe's behavior on set." The next year, US Weekly noted that during an interview on Dax Shepard's "Armchair Expert" podcast, Bush hinted that there were serious issues on set.
"I feel like I was standing butt naked, bruised and bleeding in the middle of Times Square, screaming at the top of my lungs and not a single person stopped to ask if they could help me," she explained. She added that the experience was "a consistent onslaught barrage of abusive behavior."
Deadline reported that Beghe faced "numerous accusations from cast and crew members," including sexual assault. Consequently, he was investigated for "inappropriate behavior" by NBC and Wolf Entertainment.
Following the investigation, Beghe apologized for his actions and said he was working on his issues. "I am deeply sorry for my behavior, which I know has been hurtful to my friends and colleagues," he said, per Deadline.
