President Barack Obama campaigned on a pledge of expanded government transparency, yet his administration has charged more Americans with violating the Espionage Act by leaking classified information than all previous administrations combined.
Eight Americans have faced charges since 2008 under the nearly 100-year-old act.
"Leaks related to national security can put people at risk," Obama said earlier this year. "I make no apologies and I don't think the American people will expect me as commander in chief not to be concerned about information that might compromise their missions or get them killed."
Here's a look at the people charged during Obama's administration with leaking information under the Espionage Act:
A former CIA employee, Sterling allegedly disclosed information about Iran's nuclear program to New York Times reporter James Risen. Speaking to a journalism class in June this year, Sterling maintained his innocence and claimed he was never the source of information for the Times report. His trial is on hold while courts deliberate whether Risen can be forced to testify in the case. Sterling faces six charges under the Espionage Act that carry a maximum of 10 years each in prison. Four other charges include penalties of a possible 20-year sentence and fines up to $250,000.
A former Navy linguist contractor, Hitselberger was charged with retaining classified information and shipping it back to Stanford University, which maintains a collection there in his name. One report said the classified documents contained "sensitive information about troop positions, gaps in U.S. intelligence and commanders' travel plans." He is being detained without bail. The court overseeing his case recently allowed him to visit the Library of Congress "to conduct research in aid of his defense, and for no other purpose." His trial date has not been set.
