As part of its publicity push ahead of its interview with Apple CEO Tim Cook tonight, ABC News has posted an excerpt of Cook's discussion with ABC News reporter David Muir.

In the clip, Cook discusses the NSA's surveillance operations and says that the Government does not have any direct access to Apple's servers and that "they would have to cart us out in a box" for that to happen.

DAVID MUIR: "What is your biggest concern — with the surveillance program here in this country?" TIM COOK: "I've been pushing very, very hard to open the books and be totally transparent. Much of what has been said isn't true; there is no back door. The government doesn't have access to our servers. They would have to cart us out in a box for that. And that just will not happen. We feel that — strongly about it. But I do want to be transparent, because I think transparency would help put everything in perspective." DAVID MUIR: "Do you think Americans, Tim, would be more at ease if you could tell them more?" TIM COOK: "I do."

This morning, ABC ran a longer preview of the interview during Good Morning America and the full piece will air tonight at 6:30 PM Eastern on World News with Diane Sawyer.
