Former FBI Deputy Director Dan Bongino confessed in an interview Tuesday that he lives in constant fear that he’ll face retaliation after he shed light on corruption in the bureau and because of a document he found related to Crossfire Hurricane.

Bongino, who left the bureau in January after roughly 10 months in the job, said he found the document in a burn bag that was related to the FBI probe into allegations of Russia collusion in President Donald Trump's 2016 campaign.

The former deputy director claimed on the "Hang Out with Sean Hannity" podcast that the document was clearly meant to be destroyed because it contained information that was "basically the keys to the kingdom on Crossfire."

“It was the mother lode,” Bongino told Hannity. “And the document was so sensitive we were not even to carry it outside of the office. I will never be the same. I’m being as serious as a stroke right now. I’m really, I’m scared.

"Don’t think for a second that I don’t think every day, and this is what’s really sad … that they’re going to come for me,” he added. “Like I’ll probably be in some federal prison. That’s what comes to my mind every day. I live like this the rest of my life because I know how they are.” 

Bongino said the roughly 100-page document reshaped his understanding of the probe and that he was "scared" by how many people were involved and did not speak up.
