WASHINGTON: The US State Department says it is studying the computer hard drives used by an army Department spokesman P. J. Crowley said that the Bureau of Diplomatic Security is helping in the analysis of the data stored on hard drives from computers believed to have been used by Army Spc. Bradley Manning, 22. Manning, who has not been charged with any crime, is being detained in Kuwait pending an army investigation of unauthorized leaks of classified information. Former computer Hacker Adrian Lamo says Manning claimed that he downloaded 260,000 classified State Department cables and transmitted them by computer to the website Wikileaks.org.
