WASHINGTON—The U.S. government’s sweep-up of Jan. 6 suspects has led to conflict within the Federal Bureau of Investigation over the agency’s expansive efforts to pursue charges against more than 1,000 people, according to a review of testimony by three former or suspended bureau employees before a House committee and other people familiar with the matter.
The investigation into a pro-Trump mob’s Jan. 6, 2021, assault on the Capitol, two weeks before President Biden’s inauguration, is the largest in FBI history in terms of the
number of cases and national reach. Prosecutors have said they may indict another thousand people in addition to those already charged. Led by agents in Washington, all 56 field offices were enlisted to help trace the rioters in the months after the attack.
