The FBI released 412 pages of documents on its case against former Trump campaign adviser Carter Page - the evidence it used to win a surveillance order that lies at the heart of Republican claims of bias in the Department of Justice.
The FBI told the court that Page "established relationships with Russian government officials, including Russian intelligence officers", and Page "has been collaborating and conspiring with the Russian government".
One-time advisor of US president-elect Donald Trump Carter Page addresses the audience during a presentation in Moscow, Russia, December 12, 2016.
Page, 47, has denied being a Russian agent.
The documents released said "the Federal Bureau of Investigation believes that the Russian Government's efforts are being coordinated with Page and perhaps other individuals associated with" Trump's campaign.
Material in a FISA warrant is considered highly classified, and the Foreign Intelligence Surveillance Court proceedings are also conducted in secret. Democrats, on the other hand, refuted this claim in their memo, saying that this was not at all why the Yahoo News article was referenced.
House Democratic Leader Nancy Pelosi said on Saturday that "these documents provide clear evidence of 'Russia's coordination with Carter Page, ' a high-ranking Trump campaign official, 'to undermine and improperly and illegally influence the 2016 USA presidential election'". "The F.B.I. believes Page has been the subject of targeted recruitment by the Russian government".
