If the CIA is going to disrupt future terrorist attacks, it needs to recruit spies to infiltrate those groups in order to disrupt the terrorist attacks. Not to rely on what you and I are putting in chat messages on Google or Apple.

The big issue is this incremental whittling away of our constitutional rights, our most important constitutional rights, including freedom of speech. This is something that we really have to put our foot down on, and we have to fight it at every step of the way.

You can't just blurt the information out to the Russian foreign minister and the Russian ambassador. What happens is, the information goes back to the CIA, to the originating office. The CIA will pull the relevant information out of the report, put it on a new blank sheet of paper and then type at the top, "Secret releasable to Russia." That way, nobody gets in trouble, no sources and methods are revealed, everybody's happy, and we can establish something of a liaison relationship to the Russians. That's not what the president did.

I think the president, very simply, has never read a copy of the Constitution. I think that that's true. He's just never bothered to read the Constitution, and he just has no understanding and appreciation of the First Amendment's protections for freedom of speech.

Even if torture works, it cannot be tolerated -- not in one case or a thousand or a million. If their efficacy becomes the measure of abhorrent acts, all sorts of unspeakable crimes somehow become acceptable. I may have found myself on the wrong side of government on torture. But I'm on the right side of history. There are things we should not do, even in the name of national security. One of them, I now firmly believe, is torture.

I can remember only a small handful of instances in which I talked about politics with my parents. I remember my parents telling me that Daniel Ellsberg was a hero when I was six years old.
