The Justice Department released on Saturday more than 400 pages of top-secret documents pertaining to the FISA warrant obtained to surveil former Trump campaign aide Carter Page.

The documents were first obtained by the New York Times through a Freedom of Information Act request.

"This application targets Carter Page,” the document said. “The F.B.I. believes Page has been the subject of targeted recruitment by the Russian government.”

Included within the previously classified documents are the 2016 application for the FISA warrant taken out on Page in addition to three renewal applications.

The FBI and the Justice Department relied heavily on the now-infamous dossier authored by former British spy Christopher Steele in obtaining the FISA warrant on Page.

Republicans have often cited the use of the dossier as misinformation used to improperly monitor President Trump and his campaign during the months leading up to the 2016 presidential election.
