The Second Leaker

The FBI has identified an employee of a federal contracting firm suspected of being the so-called "second leaker" who turned over sensitive documents about the U.S. government's terrorist watch list to a journalist closely associated with ex-NSA contractor Edward Snowden.

[...]

The FBI recently executed a search of the suspect's home, and federal prosecutors in Northern Virginia have opened up a criminal investigation into the matter, the sources said.

[...]

Contacted Monday, [the Intercept reporter who broke the watch list story, [Jeremy] Scahill declined any comment about his source, but said neither he nor The Intercept had been notified by federal officials about the investigation. He added, however, that he is not surprised to learn of the probe: "The Obama administration in my view is conducting a war against whistleblowers and ultimately against independent journalism."

This article also references a remark Eric Holder made regarding the persecution of New York Times reporter James Risen:

"As long as I am attorney general, no reporter who is doing his job will go to jail," Holder said at a meeting with news media representatives when asked about the Risen case.

And that immediately rung a bell for me. I’d asked why Eric Holder had decided to resign. Perhaps he wasn’t willing to do the administration’s bidding and was “asked” to leave.
