On Friday, the heads of the CIA and FBI, plus Director of National Intelligence James Clapper, are scheduled to brief President-elect Donald Trump on a 50-page classified report on Russian hacking, a day after President Obama was presented with the same findings from the U.S. intelligence community. The meeting could be awkward. Trump has publicly questioned the intelligence community's findings that Russia hacked Democrats and leaked their documents in part to help him win the election, though on Thursday he did tweet he is "a big fan" of "Intelligence." In a Senate hearing on Thursday, Clapper and other intelligence agency leaders said they were confident about Russia's meddling in the election, and the classified summation reportedly includes pretty solid evidence, including the identifications of those who delivered hacked emails from Russia to WikiLeaks.
