President Trump’s national security adviser said Saturday he “would not be concerned” about having a backchannel communications system with Russia, following reports that Jared Kushner, Trump’s son-in-law and senior adviser, had discussed setting up a secret communications channel with Russian officials.

H.R. McMaster told reporters during a press briefing in Italy on Saturday that the U.S. frequently sets up backchannels with other countries to allow for discreet communications.
