In a wide-ranging interview with NBC "Nightly News" anchor Brian Williams that aired Wednesday night, former NSA contractor Edward Snowden said he sees himself as a patriot who leaked classified documents to inform the American public about surveillance programs that violated the U.S. Constitution.

"But I've gained the ability to go to sleep at night and to put my head on the pillow and feel comfortable that I've done the right thing even when it was the hard thing."
