The CIA has concluded that Russia mounted a covert intelligence operation to help Donald Trump win the U.S. election, a congressional official knowledgeable on the matter told NBC News. Director of National Intelligence James Clapper described the latest findings on the intentions of the Russian government in a closed-door briefing with senators last week, according to the official. The president-elect’s transition team responded by impugning the CIA’s integrity in a statement Friday, calling the spy agency ‘the same people that said Saddam Hussein had weapons of mass destruction.’
