Three FBI employees told Circa they personally witnessed McCabe make disparaging remarks about Flynn before and during the time the retired Army general emerged as a figure in the Russia case.

The bureau employees, who spoke only on condition of anonymity for fear of retribution, said they did not know the reason for McCabe’s displeasure with Flynn, but that it made them uncomfortable as the Russia probe began to unfold and pressure built to investigate Flynn. One employee even consulted a private lawyer.

“As far as the troops in the field, the vast-majority were disgusted with the Russia decision, but that was McCabe driving the result that eventually led [former FBI Director James] Comey to make the decision,” said a senior federal law enforcement official, with direct knowledge of the investigation.
