The acting DOJ official behind a potential witch hunt against prosecutors and FBI agents who investigated the Capitol riot worked on Jan. 6 cases himself.

A court ordered the administration to keep secret a list of F.B.I. officials who had pursued Jan. 6 rioters. Then Trump said he would “surgically” fire some agents.

FBI employees and the Justice Department reached a tentative deal to prevent the Trump administration from publicly releasing the names of personnel involved in investigating the Jan. 6 Capitol attack.

Ed Martin, a loyal Trump soldier, oversees the U.S. attorney’s office, which is likely to help turn the investigative powers of the government on several of the president’s perceived enemies.
