Q3131 3132 Follow the Attorney - Nick Lewin was Advisor for Mueller and then Special Counsel for Comey From his Bio -  In May of 2012, I accepted another long-term assignment, as Special Counsel to FBI Director Robert Mueller, and served for about a year-and-a-half as his advisor on a wide variety of national security matters. After Director Mueller left, I served briefly as special counsel to Director James Comey, before returning to SDNY. Serving as the Directors’ Special Counsel was just as interesting as it sounds. And it was a personal honor to serve Directors Mueller and Comey.  (https://law.yale.edu/studying-law-yale/alumni-student-profiles/nicholas-lewin-04)
