Attorney General Jeff Sessions has told associates he wants to put the entire National Security Council staff through a lie detector test to root out leakers. It's unclear whether this will ever happen, but Sessions floated the idea to multiple people, as recently as last month.

Sessions' idea is to do a one-time, one-issue, polygraph test of everyone on the NSC staff. Interrogators would sit down with every single NSC staffer (there's more than 100 of them), and ask them, individually, what they know about the leaks of transcripts of the president's phone calls with foreign leaders. Sessions suspects those leaks came from within the NSC, and thinks that a polygraph test — at the very least — would scare them out of leaking again.

Sessions has told associates he likes the idea of targeting the foreign leader phone calls because there's a small enough universe of people who would have had access to these transcripts. Also, the idea that the President of the United States can't have private conversations with foreign leaders was a bridge too far, even for Democrats.

Ian Prior, a spokesman for Sessions, declined comment when presented with the details of this report.

Why this matters: That Sessions would seriously entertain such a startling action reveals how frustrated he's become about the rampant leaking of classified information. Leak probes like the one Sessions announced at a big press conference on August 4 have happened under previous administrations, and rarely with any significant success. In fact, they can even backfire – look no further than the leak probe that ensnared James Cartwright, Obama's favorite general. Obama later pardoned Cartwright. So much for cracking down on leakers.

Bottom line: Sessions seems to understand that it's extremely tough to successfully prosecute leakers, especially when they are career intelligence professionals who are skilled at covering their digital tracks.
