Noah Wyle, star doctor on "The Pitt," says he only found out about changes to the show's controversial ICE episode after the edits had been negotiated with HBO.

The March 19 episode, titled "5:00 p.m.," featured ICE agents bringing a detained patient into the Pittsburgh emergency room, causing fear and disruption for the patients and medical staff, and resulting in the arrest of a nurse.

Executive producer John Wells previously revealed that HBO had requested changes to the episode spotlighting the hot-button political topic.

Speaking to Variety in a story published April 9, Wyle, who is an executive producer on the show, said he was initially alarmed when he learned about the changes.

"The negotiation was being driven by political reasons, creative reasons, fear, uncertainty, all sorts of legitimate reasons," Wyle said. "I’ll be honest and say that I was concerned about the edits we were making initially."
