The Daily Beast reports:
A former National Security Council official now working for Attorney General Jeff Sessions explored ways to surreptitiously monitor the communications of White House staff for leaks or perceived political disloyalty to Donald Trump, according to three former Trump NSC officials familiar with the effort.
Ezra Cohen-Watnick, whom former national security adviser Michael Flynn brought onto the NSC as senior director for intelligence, sought technical solutions in early 2017 for collecting and analyzing phone and other data on White House colleagues for interactions with reporters.
He portrayed his desired leak hunt as an “insider threat” detection effort, according to the ex-officials. Those who heard of it presumed it would focus on NSC staffers held over from the Obama administration.
