The FISC [Foreign Intelligence Surveillance Court] admitted that two of the spy warrants against Carter Page were not lawfully authorized as the FISA law states that American citizens cannot be secretly spied on by the US government absent probable cause that an American is unlawfully acting as a foreign agent.
Judicial Watch finally obtained the FISA warrants they requested. The documents are heavily redacted, but do show that the discredited Steele dossier was the primary evidence used to obtain the warrant and three renewal warrants. James Clapper connects Obama to the Steele dossier, ‘spygate’ and the Mueller investigation.
Journalist Lee Stranahan reports that Carter Page, the subject of the FISA wiretap warrant, was an FBI employee from 2013 to 2016 who targeted the Russians prior to joining the Trump campaign. Therefore, when the FBI obtained the FISA warrant against Page, it was aware that he was not a Russian agent.
