WASHINGTON — The Trump-appointed leaders of the FBI deepened their purge of employees this week, forcing out senior agents, including the former acting head of the bureau and another top official whose ascent angered Trump supporters, according to people familiar with the matter.

Brian Driscoll, who briefly served as the acting director in the early days of the Trump administration, was among those being forced out and told to leave by today, according to the people, who spoke on condition of anonymity to describe personnel decisions that have not yet been made public.

Steven J. Jensen, the head of the FBI’s Washington field office, was also ousted this week, these people said. Jensen had been a target of conservatives because in overseeing the bureau’s domestic terrorism operations section at the time, he played a key role in responding to the Jan. 6, 2021, attack on the Capitol.

Driscoll, a charismatic FBI veteran with extensive experience in domestic and international investigations, became an unlikely champion of the bureau after being accidentally catapulted to the director’s chair on Inauguration Day.

He resisted demands to turn over the names of FBI agents who had worked on the investigation into the Capitol attack.
