(CNN) CIA Director Mike Pompeo recently met -- at the urging of President Donald Trump -- with one of the principal deniers of Russian interference in the US election, according to multiple intelligence sources.

Trump apparently made the highly unusual request that Pompeo meet with the former National Security Agency employee and look into a theory that the leak of Democratic Party emails last year was an inside job rather than a cyberattack by Russian hackers.

William Binney, the former NSA employee-turned-whistleblower who circulated the conspiracy theory, confirmed to CNN that he met with Pompeo for about an hour on October 24 -- despite the fact the intelligence community concluded early this year that Russia interfered in the 2016 presidential election.
