Former Director of National Intelligence James Clapper was the source of a major leak to CNN, and he lied about it to Congress, President Donald Trump, and the public, according to a report by the House intelligence committee released on April 27.
The leak to CNN resulted in the publication of the infamous dossier on Trump, which, in turn, became the foundation of the narrative that the Trump campaign colluded with Russia. The committee concluded, after a yearlong investigation, that no collusion occurred.
