ABC’s Stephanopoulos to interview Baldwin on set shooting

George Stephanopoulos of ABC News conducted an hour-long interview with Alec Baldwin to air Thursday about the shooting on the set of the movie "Rust."

Baldwin fired a prop gun that had live ammunition on the set in New Mexico on Oct. 21, killing cinematographer Halyna Hutchins and injuring director Joel Souza.

Alec Baldwin told ABC’s George Stephanopoulos in an interview airing Thursday that he did not pull the trigger on a prop gun he was holding on a New Mexico film set when it went off, killing a cinematographer.

"I didn’t pull the trigger," Baldwin said. "I would never point a gun at anyone and pull the trigger at them. Never."

It is Baldwin’s first sitdown interview since the Oct. 21 shooting on the set of the western film "Rust." Authorities have said Baldwin was told the gun was safe to handle but continue to investigate how a live round ended up in the weapon.

ABC released a clip Wednesday that shows Baldwin breaking down in tears while describing Halyna Hutchins, the cinematographer who was killed on the set. Director Joel Souza was also wounded.

He said in response to a question about how a live round ended up on the set: "I have no idea. Someone put a live bullet in a gun, a bullet that wasn’t even supposed to be on the property."

It will be the first time Baldwin has spoken in depth on screen about the shooting. The interview will air on ABC at 8 p.m. Eastern time on Thursday and stream on Hulu later that evening.

ABC said a two-hour special "20/20" next week will examine the investigation into the shooting in more depth.
