National Security Adviser H.R. McMaster on Saturday said he "would not be concerned" by backchannel communications with Russia, though he declined to specifically comment on allegations that President Trump's son-in-law and senior adviser Jared Kushner unsuccessfully attempted to arrange a secret communication channel between the Trump transition team and the Kremlin shortly after the election.
National Economic Council Director Gary Cohn and Press Secretary Sean Spicer also refused to discuss Kushner at Saturday's media briefing. "We're not going to comment on Jared," said Cohn. "We're just not going to comment."
McMaster did note the U.S. has "backchannel communications with a number of countries," though Kushner was a private citizen and not an authorized representative of Washington at the time when he allegedly spoke with Russian Ambassador Sergey Kislyak.
