Glenn Greenwald's new site devoted to the security leaks of Edward Snowden and broader "adversarial journalism" has launched as The Intercept.

The site is led by Greenwald and two other noted investigative journalists - Laura Poitras and Jeremy Scahill. Scahill takes the lead bylines with Greenwald on the site's first major story - an investigation of the NSA's role in locating targets for U.S. drone strikes.

In an initial post entitled "Welcome to The Intercept," Greenwald, Poitras and Scahill lay out the editorial vision for the site. In the short term, The Intercept will "provide a platform and an editorial structure in which to aggressively report on the disclosures provided to us by our source, NSA whistleblower Edward Snowden," they wrote in a blog post on the site.

While the Snowden leak has already formed the basis of a large number of revelations about U.S. surveillance efforts, this may just be the tip of the iceberg. As more information about the leak comes to light, the scope of Snowden's theft has grown. Lawmakers recently claimed Snowden took about 1.7 million files.

The broader vision for the site includes the type of investigative journalism for which Greenwald, Poitras and Scahill have become know.

"Our longer-term mission is to provide aggressive and independent adversarial journalism across a wide range of issues, from secrecy, criminal and civil justice abuses and civil liberties violations to media conduct, societal inequality and all forms of financial and political corruption," they wrote in a blog post.

The Intercept is the first in a series of "digital magazines" that will be launched by Pierre Omidyar's First Look Media. Future sites will cover topics from sports and entertainment to business and politics.

Greenwald left The Guardian in late 2013 to join the efforts of Omidyar, who founded eBay and has a net worth of $8.5 billion, according to Forbes.
