Ambassador Sergei Kislyak reported to his superiors in Moscow that Kushner, then President-elect Trump’s son-in-law and confidant, 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.
The meeting also was attended by Michael Flynn, Trump’s first national security adviser.
The White House disclosed the fact of the meeting only in March, playing down its significance. But people familiar with the matter say the FBI now considers the encounter, as well as another meeting Kushner had with a Russian banker, to be of investigative interest.
