White House Press Secretary Sarah Sanders said Trump had ordered the documents released by the Office of the Director of National Intelligence (ODNI) and the Justice Department "[a]t the request of a number of committees of Congress, and for reasons of transparency."
The documents to be declassified also include all FBI reports on interviews with Justice Department official Bruce Ohr and all FBI reports of interviews prepared in connection with all other applications to surveil Carter Page.
Trump also ordered the Justice Department to release text messages from a number of the key players in the Russia investigation "without redaction" -- including Ohr, Strzok, Lisa Page, former FBI Director James Comey and former FBI Deputy Director Andrew McCabe.
The 21 pages only make up a small part of the 412 pages of FISA applications and warrants related to Page released by the FBI earlier this year in heavily redacted format. The June 2017 application was the last of four filed by the Justice Department in support of FISA court orders allowing the monitoring of Page for nearly a year.
