The New Yorker profiles President-elect Donald Trump’s national security adviser Michael Flynn:

Flynn broke rules he thought were stupid. He once told me about a period he spent assigned to a C.I.A. station in Iraq, when he would sometimes sneak out of the compound without the “insane” required approval from C.I.A. headquarters, in Langley, Virginia. He had technicians secretly install an Internet connection in his Pentagon office, even though it was forbidden. There was also the time he gave classified information to NATO allies without approval, an incident which prompted an investigation, and a warning from superiors. During his stint as Mullen’s intelligence chief, Flynn would often write “This is bullshit!” in the margins of classified papers he was obliged to pass on to his boss, someone who saw these papers told me.

The greatest accomplishment of Flynn’s military career was revolutionizing the way that the clandestine arm of the military, the Joint Special Operations Command, undertook the killing and capture of suspected terrorists and insurgents in war zones. Stanley McChrystal, Flynn’s mentor, had tapped him for the job. They were both part of the self-described “Irish mafia” of officers at the Fort Bragg Army base, in North Carolina.
