Horowitz's investigation on the bureau's probe into the now debunked theory that Trump colluded with Russia in the 2016 presidential election will more than likely result in the declassification of documents - requested by senior Republican lawmakers for more than several years. These are the same documents President Trump turned over to Attorney General William Barr in May,  giving him 'full and complete authority" to declassify.

Those documents will contain several classified pages of the Foreign Intelligence Surveillance Act on former Trump campaign advisor Carter Page, exculpatory evidence that was withheld from the Foreign Intelligence Surveillance Court, the so-called 'Gang of Eight' folder (which contained exculpatory information), as well as the email chain between FBI investigators in the Russia probe and then-FBI Director James Comey. Those emails also include discussions with lawyers in the DOJ's national security division. As previously reported, the email chains will contain information that prove the FBI knew prior to obtaining a warrant to spy on Page that former British spy Christopher Steele's information in his infamous dossier on Trump could not be proven.
