Fox News ran a quick segment where Corespondent John Roberts deduces who the White House Leaker can be.
Initially, reports were that Reince Priebus had reached out to the FBI, but John Roberts rebuts that and says that it was actually FBI Deputy Director Andrew McCabe that reached out to the White House. In that communication, McCabe is alleged to have told the White House that the New York Times stories and others about Russian communications with White House Officials during the transition was “all a bunch of b.s.”
Roberts says only 3 people would have had knowledge of the information; Andrew McCabe (FBI), James Comey (FBI), or Reince Priebus (White House). The leaker would have to be one of the 3 or someone on Priebus’s staff.
