Last month, McCabe sued the FBI and the Justice Department over his firing, arguing it was part of Trump's plan to rid the bureau of leaders he perceived as disloyal to him. McCabe argued in his complaint that the two officials responsible for demoting and then firing McCabe – FBI Director Chris Wray and Sessions – created a pretext to force him out in accordance with the president's wishes.
The stated reason for the firing was that McCabe had misled investigators over his involvement in a news media leak, but McCabe says the real reason was "his refusal to pledge allegiance to a single man."
