Despite that early controversy, Cohen-Watnick retains one of the most consequential intelligence jobs in the nation, and his influence is rising. He is in the thick of some of the most important policy fights at the White House; he is viewed as an Iran hawk and has been characterized, for instance, as a main proponent of expanding U.S. efforts against Iran-backed militias in Syria. And beyond policy specifics, he’s become a flashpoint in the long-running tension between Trump and the intelligence community, a part of the U.S. government that the president has at times openly disdained.

Yet what we don’t know about Cohen-Watnick far outstrips what we do. Was he a central player in the Nunes scandal, or just a bystander? Has he retained his job due to his talent, or is he being protected because he’s advancing the agenda of powerful West Wing patrons? What, besides loyalty to the president, are his credentials? Is he Flynn’s mole on the council, or does he not even know the deposed national-security adviser all that well? Is he brash and difficult to work with, or modest and brilliant? And perhaps most important: Now that he has the president’s ear, what will he whisper into it?
