Alec Baldwin: Key question is who put live round in 'Rust' gun

Alec Baldwin said the only issue that matters in the shooting that killed a cinematographer on a New Mexico movie set is how the bullet ended up in the gun.

"There's only one question to be resolved, and that's where did the live round come from?" Baldwin said in an ABC interview with George Stephanopoulos that aired Thursday night, the first time the actor has spoken in depth on screen about the Oct. 21 shooting on the set of the Western "Rust."

Baldwin said in a clip from the interview released Wednesday that he did not pull the trigger of the gun he was holding that went off and killed cinematographer Halyna Hutchins and wounded director Joel Souza.

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

Baldwin said he and Hutchins "had something profound in common. We both assumed the gun was empty. "
