Classified documents presented last week to President Obama and President-elect Trump included allegations that Russian operatives claim to have compromising personal and financial information about Mr. Trump, multiple US officials with direct knowledge of the briefings tell CNN.
The allegations were presented in a two-page synopsis that was appended to a report on Russian interference in the 2016 election. The allegations came, in part, from memos compiled by a former British intelligence operative, whose past work US intelligence officials consider credible. The FBI is investigating the credibility and accuracy of these allegations, which are based primarily on information from Russian sources, but has not confirmed many essential details in the memos about Mr. Trump.
The classified briefings last week were presented by four of the senior-most US intelligence chiefs — Director of National Intelligence James Clapper, FBI Director James Comey, CIA Director John Brennan, and NSA Director Admiral Mike Rogers.
