Getting this wasn't easy. After several bouts with "BoozAllen.com Is Undergoing Maintenance" during an apparently crashing-under-the-weight-of-inquiring-people-want-to-know moment, I finally made it through to their press release (bolding mine):
Booz Allen Statement on Reports of Leaked Information
June 9, 2013
Booz Allen can confirm that Edward Snowden, 29, has been an employee of our firm for less than 3 months, assigned to a team in Hawaii. News reports that this individual has claimed to have leaked classified information are shocking, and if accurate, this action represents a grave violation of the code of conduct and core values of our firm. We will work closely with our clients and authorities in their investigation of this matter.
Here is Glenn Greenwald's interview at The Guardian: Edward Snowden: the whistleblower behind the NSA surveillance revelations, where there is also video:
The 29-year-old source behind the biggest intelligence leak in the NSA's history explains his motives, his uncertain future and why he never intended on hiding in the shadows [...]

Another controversy, related to some of the senior staff of Booz Allen (past and present) and related to its performance on some specific U.S. intelligence agency contracts, was brought to light on January 12, 2007 in an interview conducted by Democracy Now! with Tim Shorrock, an independent investigative journalist, and separately in an article he wrote for the Salon online magazine. Through investigation of Booz Allen employees, Shorrock asserts that there is a sort of revolving-door conflict of interest between Booz Allen and the U.S. government, and between multiple other contractors and the U.S. government in general. Regarding Booz Allen, Shorrock referred to such people as John M. McConnell, R. James Woolsey, Jr., and James R. Clapper, all of whom have gone back and forth between government and industry (Booz Allen in particular), and who may present the appearance that certain government contractors receive undue or unlawful business from the government, and that certain government contractors may exert undue or unlawful influence on government. Shorrock further relates that Booz Allen was a sub-contractor with two programs at the U.S. National Security Agency (NSA), called Trailblazer and Pioneer Groundbreaker.
