Director of National Intelligence James Clapper on Wednesday reaffirmed to President-elect Trump that although the 35-page dossier that Buzzfeed published on Tuesday has been circulating around the federal government for months, it is not an official intelligence community product and was likely not leaked by intelligence employees.

"I emphasized that this document is not a U.S. Intelligence Community product and that I do not believe the leaks came from within the IC. The IC has not made any judgment that the information in this document is reliable, and we did not rely upon it in any way for our conclusions," Clapper said in a statement.

"I expressed my profound dismay at the leaks that have been appearing in the press, and we both agreed that they are extremely corrosive and damaging to our national security," Clapper added.

Trump "again affirmed" his appreciation for the Intelligence Community and Clapper told him the agencies are working to provide the "fullest possible picture of any matters that might affect national security."

Trump praised Clapper on Thursday morning by saying Clapper called him and denounced the report.

Trump was briefed by Clapper and leaders of the FBI, CIA and NSA last Friday about the role Russia played in hacking Democratic officials' during the election. Up until this week, Trump has refused to say whether Russia was to blame for the hackings, but admitted in a press conference on Wednesday that they were likely involved.

The incoming GOP president has expressed concern about leaks of intelligence documents, some of which have hit the media and public despite being classified information, prompting Trump to lash out at the intelligence organizations publicly.
