Several senior FBI officials have been told to leave the agency or expect to be fired next week, according to multiple news reports Thursday, as President Donald Trump ’s administration executes his long-touted plans to overhaul the federal government.

The officials reportedly included executive assistant directors and top agents in field offices, including some who oversee national security and criminal investigations and were promoted by former FBI Director Christopher Wray.

The affected employees include about a half-dozen “executive assistant directors,” who are some of the bureau’s top managers.
