WASHINGTON — The Trump administration on Friday fired a group of prosecutors involved in the Jan. 6 criminal cases and demanded the names of FBI agents involved in those same probes so they can possibly be ousted, moves that reflect a White House determination to exert control over federal law enforcement and purge agencies of career employees seen as insufficiently loyal.

Acting Deputy Attorney General Emil Bove ordered the firings of the Jan. 6 prosecutors days after President Donald Trump’s sweeping clemency action benefiting the more than 1,500 people charged in the U.S. Capitol attack, according to a memo obtained by The Associated Press. About two dozen employees at the U.S. attorney’s office in Washington were terminated, according to a person familiar with the matter who spoke on the condition of anonymity because they were not authorized to discuss personnel matters.

A separate memo by Bove identified more than a half-dozen FBI senior executives who were ordered to resign or be fired by Monday, and also asked for the names and records related to all agents who worked on investigations into the Jan. 6, 2021, U.S. Capitol riot — a list the bureau’s acting director said could number in the thousands. Bove, who was defended Trump in his criminal cases before joining the administration, said Justice Department officials would then carry out a “review process to determine whether any additional personnel actions are necessary.”

“As we’ve said since the moment we agreed to take on these roles, we are going to follow the law, follow FBI policy, and do what’s in the best interest of the workforce and the American people — always,” Acting FBI Director Brian Driscoll wrote in a letter to the workforce.

The prosecutors who were fired in the D.C. U.S. attorney’s office had been hired for temporary assignments to support the Jan. 6 cases, but were moved into permanent roles after Trump’s presidential win in November, according to the memo obtained by the AP. Bove, the acting deputy attorney general, said he would not “tolerate subversive personnel actions by the previous administration.”

Any mass firings at the FBI would be a major blow to the historic independence from the White House of the nation’s premier federal law enforcement agency and would reflect Trump’s persistent resolve to bend the law enforcement and intelligence community to his will.
