FBI Director Kash Patel called out the left-wing media Saturday for labeling him a liar over his discovery of a trove of sensitive documents related to the origins of the Trump-Russia probe buried in multiple "burn bags" in a secret room inside the bureau.Sources previously told Fox News Digital the "burn bag" system is used to destroy documents designated as classified or higher.Sources also said multiple burn bags were found and filled with thousands of documents. One document FBI officials found in a burn bag, sources said, was the classified annex to former special counsel John Durhams final report, which includes the underlying intelligence he reviewed.Patel addressed the burn bags on X, reminding people of what he proved in 2017 and 2018.SOROS' ALLEGED TIES TO RUSSIAGATE EXPOSED IN DECLASSIFIED ANNEX OF DURHAM REPORT"In 2017/18, I proved the Steele Dossier was fictitious intelligence, weaponized by corrupt FBI officials to deceive a federal judge and unlawfully spy on then presidential candidate Trumps campaign all paid for by his opponent," the FBI director said. "The media called me a liar."Now Im the FBI Director: We just uncovered burn bags/room filled with Russia Gate files, including the Durham annex, and declassified them," Patel continued. "Once again, I released the prior FBIs own documents and exposed the truth. The same media is calling me a liar again. Maybe this FBI will release more docs directly, from FBI HQso we can see who is lying wouldnt want to deprive the fake news of more bogus Pulitzers."The declassification of the classified annex is being done in close coordination between CIA Director John Ratcliffe, Patel, Director of National Intelligence Tulsi Gabbard, Attorney General Pam Bondi and acting National Security Agency Director William Hartman.PATEL FOUND THOUSANDS OF SENSITIVE TRUMPRUSSIA PROBE DOCS INSIDE 'BURN BAGS' IN SECRET ROOM AT FBIThe declassified annex will be transmitted to Senate Judiciary Committee Chairman Chuck Grassley, who ultimately will release the document to the public.Patel, in a June interview with podcast host Joe Rogan, revealed that he found a room full of documents and computer hard drives "that no one had ever seen or heard of.""Just think about this," Patel told Rogan. "Me, as director of the FBI, the former 'Russiagate guy,' when I first got to the bureau, found a room that Comey and others hid from the world in the Hoover Building, full of documents and computer hard drives that no one had ever seen or heard of. Locked the key and hid access and just said, 'No one's ever gonna find this place.'"Patel and his staff have been working through the documents, some of which are related to sensitive investigations, including the FBIs original TrumpRussia probe, known inside the bureau as Crossfire Hurricane.FBI'S CONTROVERSIAL TRUMP-RUSSIA ACTIONS PREDICTED WITH 'ALARMING SPECIFICITY' BY FOREIGN ACTORS: SOURCESIt is unclear what the latest documents cover specifically, but sources told Fox News Digital that the most recent discovery was pursuant to an investigative request from Grassley.Patel has turned the documents over to Grassley.Grassley has been requesting information related to Durhams probe.
