Leak investigation regarding Flynn-Kislyak calls has been closed without charges: NYT report

A leak investigation bearing the code-name Operation Echo, which pertained to a Washington Post column about 2016 telephone calls between Michael Flynn and then-Russian Ambassador to the U.S. Sergey Kislyak, was reportedly closed, according to the New York Times.

The outlet reported the news in a story that was about a separate matter related to Sen. Richard Burr: "The Justice Department’s decision in the Burr case came after prosecutors in Washington quietly closed two other politically fraught cases this fall without charges, a person familiar with the matter said on Tuesday when asked about other delicate cases," the New York Times reported.

Acting U.S. Attorney in Washington Michael R. Sherwin approved shutting Operation Echo, as well as a separate case involving Walid Phares, based on the recommendations of prosecutors, the New York Times said, citing an individual "familiar with the investigations."
