Jared Kushner and Russia’s ambassador to Washington discussed the possibility of setting up a secret and secure communications channel between Trump’s transition team and the Kremlin, using Russian diplomatic facilities in an apparent move to shield their pre-inauguration discussions from monitoring, according to U.S. officials briefed on intelligence reports.

Ambassador Sergey Kislyak reported to his superiors in Moscow that Kushner, son-in-law and confidant to then-President-elect Trump, made the proposal during a meeting on Dec. 1 or 2 at Trump Tower, according to intercepts of Russian communications that were reviewed by U.S. officials. Kislyak said Kushner suggested using Russian diplomatic facilities in the United States for the communications.

Kushner’s apparent interest in establishing a secret channel with Moscow, rather than relying on U.S. government systems, has added to the intrigue surrounding the Trump administration’s relationship with Russia.

To some officials, it also reflects a staggering naivete.

The FBI closely monitors the communications of Russian officials in the United States, and it maintains a nearly constant surveillance of its diplomatic facilities. The National Security Agency monitors the communications of Russian officials overseas.

Current and former U.S. intelligence officials said that although Russian diplomats have secure means of communicating with Moscow, Kushner’s apparent request for access to such channels was extraordinary.

“How would he trust that the Russians wouldn’t leak it on their side?” said one former senior intelligence official. The FBI would know that a Trump transition official was going in and out of the embassy, which would cause “a great deal” of concern, he added. The entire idea, he said, “seems extremely naive or absolutely crazy.”
