WASHINGTON - The FBI on Saturday released documents related to the surveillance of former Trump presidential campaign adviser Carter Page as part of a probe into whether he conspired with the Russian government to undermine the 2016 US election.The 412 pages, mostly heavily redacted and made public by the Federal Bureau of Investigation late Saturday, included surveillance applications to the Foreign Intelligence Surveillance Court and warrants surrounding the investigation into Page."The FBI believes that Page has been collaborating and conspiring with the Russian Government," the surveillance application filed in October 2016 said. The documents released include applications and renewal warrants filed in 2017 after Trump took office. Page has denied being an agent of the Russian government and has not been charged with any crime.Earlier Saturday, the New York Times reported it had received a copy from the Justice Department after it and other news organizations had filed suit.The documents released said "the FBI believes that the Russian Government's efforts are being coordinated with Page and perhaps other individuals associated with" Trump's campaign. It added Page "has established relationships with Russian Government officials, including Russian intelligence officers."
