Greg Rosen, now an attorney at Rogers Joseph O’Donnell, spoke with James Pearce, Lawfare Legal Fellow, about his time prosecuting federal crimes in the U.S. Attorney’s Office for the District of Columbia. He focused mostly on the investigation and prosecution that followed the attack of the U.S. Capitol on January 6, 2021. He discussed how the U.S. Attorney’s Office carried out the largest investigation in the history of the country, how it handled the multiple investigative and logistical challenges the prosecutions posed, and how to think about the Supreme Court’s decision holding that the congressional obstruction count charged in many Jan. 6 cases was misapplied. Rosen also weighed in on the D.C. U.S. Attorney’s under the second Trump administration.
