Glenn Greenwald, journalist who broke NSA stories, to leave Guardian newspaper

LONDON – Glenn Greenwald, the American journalist who broke the first stories about the U.S. National Security Agency's global spying program, says he is leaving the Guardian newspaper.

Greenwald described his partnership with the Guardian as "extremely fruitful and fulfilling," saying in a statement Tuesday that he would take up a new opportunity in journalism. He would not say what it is.

The Guardian called Greenwald a "remarkable" journalist and said it wishes him well.

Greenwald has written extensively about NSA surveillance programs based on files leaked by former intelligence contractor Edward Snowden.

News of Greenwald's exit was first reported by BuzzFeed.
