One source described the information as financial in nature and said the discussion centered on whether the Russians had leverage over Trump's inner circle. The source said the intercepted communications suggested to US intelligence that Russians believed "they had the ability to influence the administration through the derogatory information."

But the sources, privy to the descriptions of the communications written by US intelligence, cautioned the Russian claims to one another "could have been exaggerated or even made up" as part of a disinformation campaign that the Russians did during the election.
The details of the communication shed new light on information US intelligence received about Russian claims of influence. The contents of the conversations made clear to US officials that Russia was considering ways to influence the election -- even if their claims turned out to be false.
None of the sources would say which specific Trump aides were discussed. One of the officials said the intelligence report masked the American names but it was clear the conversations revolved around the Trump campaign team. Another source would not give more specifics, citing the classified nature of the information.
"The Russians could be overstating their belief to influence," said one of the sources.
As CNN first reported
, the US intercepted discussions of Russian officials bragging about cultivating relationships with Trump campaign aides during the campaign, including Trump's first national security adviser, Michael Flynn, to influence Trump. Following CNN's report, The New York Times said Trump's campaign chairman Paul Manafort was also discussed.
A White House spokesman told CNN: "This is yet another round of false and unverified claims made by anonymous sources to smear the President. The reality is, a review of the President's income from the last ten years showed he had virtually no financial ties at all. There appears to be no limit to which the President's political opponents will go to perpetuate this false narrative, including illegally leaking classified material. All this does is play into the hands of our adversaries and put our country at risk."
The FBI declined to comment for this story. The Office of the Director of National Intelligence and Flynn did not return calls seeking comment.

Manafort has denied he received any illicit finances and also denied any wrongdoing in connection with his work for Trump and foreign officials before joining the Trump campaign. He has offered to testify before congressional committees investigating Russia's election interference.
The FBI investigation into Russian meddling in the US election, recently handed over to Special Counsel Robert Mueller, includes seeking answers as to whether there was any coordination with associates of Trump and includes examining financial dealings of key Trump associates. The FBI would not comment on whether any of the claims discussed in the intercepts have been verified.
But US counterintelligence investigators were already looking into the Russian claims during the summer of 2016, before the public became aware of similar claims in a dossier created for political opponents of Trump by a former British spy. The former spy, Christopher Steele, shared
some of those findings with the FBI during the summer of 2016.
