The CIA has identified Russian officials who fed material hacked from the Democratic National Committee and party leaders to WikiLeaks at the direction of Russian President Vladimir Putin through third parties, according to a new U.S. intelligence report, senior U.S. officials said on Thursday.

The officials, who spoke on condition of anonymity, said the Central Intelligence Agency and others have concluded that the Russian government escalated its efforts from discrediting the U.S. election process to assisting President-elect Donald Trump’s campaign.

The intelligence assessment was presented to President Barack Obama on Thursday and will be briefed to Trump on Friday…

In some cases, one official said, the material followed what was called “a circuitous route” from the GRU, Russia’s military intelligence agency, to WikiLeaks in an apparent attempt to make the origins of the material harder to trace, a common practice used by all intelligence agencies, including U.S. ones.
