Alec Baldwin Says He Didn't Pull Trigger on Gun With Live Round

Alec Baldwin says he didn't pull the trigger on the gun that killed Halyna Hutchins, the first time we've heard him make the new claim, and leaving many more questions to be answered.

The actor is speaking out about the 'Rust' tragedy in his first sit-down interview, which will air Thursday on ABC. The network just released a teaser for what is to be discussed, and there's a lot to unpack -- including his claim that he didn't squeeze the trigger.

In a nearly 2 minute clip, you hear anchor George Stephanopoulos peppering Baldwin with questions -- and it sounds like he's asking everything that most everybody has wondered about this story ... and Alec seems to respond to much of it, oftentimes in emotional terms.

One question revolves around the alleged fact that Alec pulling the trigger during the rehearsal that day was not called for in the script ... at least according to people who've sued over this so far.

Immediately in response, Alec is heard saying ... "Well, the trigger wasn't pulled. I didn't pull the trigger." GS seems stunned, but AB insists he'd never point a gun at someone and fire. Of course, this would mean Baldwin is suggesting the gun misfired on its own.

There's not much clarity on what Alec means exactly -- but we suppose everyone will get the answer when this chat hits the airwaves tomorrow.
