Top American tech giants Google, Microsoft, Facebook and Twitter have urged the Obama administration to make its national security information more transparent. The request comes in the wake of leak of classified information about secretive governmental programs on tapping of phone records of millions of American nationals and email and internet of foreign nationals. David Drummond, Chief Legal Officer of Google, said in a letter to the US Attorney General, Eric Holder and the FBI Director, Robert Mueller that the compliance with these requests gives the US government unfettered access to the users’ data are simply untrue. However, government nondisclosure obligations regarding the number of FISA national security requests that Google receives, as well as the number of accounts covered by those requests, fuel that speculation. Microsoft, Facebook and Twitter soon came out in support of Google. A Microsoft spokesman said that permitting greater transparency on the aggregate volume and scope of national security requests, including FISA orders, would help the community understand and debate these important issues.
