FBI Deputy Director Andrew McCabe was forced to step down from his post on Monday -- and his departure has reportedly taken many FBI field agents off guard.

Appearing on CNN Monday, reporter Shimon Prokupecz said that he's heard from leaders in FBI field offices across the country who say they and their teams are frustrated that they are first hearing about these resignations through news reports and not through official channels.

"This comes as a surprise to many people," Prokupecz said of McCabe's departure. "Certainly the initial reaction from folks in the field -- and these are the field agents and the field leaders at the field offices -- is that people are pretty angry right now. They are hearing about FBI leadership moves from the news."

Prokupecz said that because news of McCabe's departure broke in the news before it was announced internally, it has added to a sense of chaos engulfing the agency.

"There is some concern among field leaders, among field agents among the FBI staff about what the hell is going on and who is running the FBI," he explained, before noting that McCabe's abrupt departure was very similar to the firing of former FBI Director James Comey.
