The Obama administration has been pursuing several major leak investigations, outpacing efforts during the Bush administration.

The Justice Department in April charged Thomas Drake, a former NSA employee, for disclosing classified information to a reporter, obstruction of justice and for making false statements.

The administration also has prosecuted Shamai Leibowitz, a former FBI translator who provided papers to a blogger, and the case of Bradley Manning, an Army specialist who allegedly transferred files to Wikileaks.

Although disclosing classified and highly sensitive information was at the heart of a Bush-era CIA leak investigation into who disclosed the identity of CIA officer Valerie Plame, the only individual charged in that case, I. Lewis "Scooter" Libby, was charged only with lying to FBI agents and a federal grand jury. Libby was not charged with disclosure of the information.
