Several top FBI officials were ousted from their jobs this week, sources familiar with the matter confirmed to ABC News, including the former acting director of the bureau who previously resisted efforts to compile a list of agents who worked on the investigation into the Jan. 6, 2021, attack on the U.S. Capitol.

Sources tell ABC News that among those informed of their terminations are former acting FBI director Brian Driscoll, assistant director in charge of the Washington, D.C. Field office Steven Jensen, and agents Walter Giardina and Christopher Meyer.

It does not appear that any were informed of the rationale behind their terminations, the sources said.
