Senator John McCain passed documents to the FBI director, James Comey, last month alleging secret contacts between the Trump campaign and Moscow and that Russian intelligence had personally compromising material on the president-elect himself.
The material, which has been seen by the Guardian, is a series of reports on Trump’s relationship with Moscow. They were drawn up by a former western counter-intelligence official, now working as a private consultant. BuzzFeed on Tuesday published the documents, which it said were “unverified and potentially unverifiable”.
The Guardian has not been able to confirm the veracity of the documents’ contents, and the Trump team has consistently denied any hidden contacts with the Russian government.
A spokesman for the Russian president, Vladimir Putin, on Wednesday denied Russia has collected compromising information on Trump and dismissed news reports as a “complete fabrication and utter nonsense”. Dmitry Peskov insisted that the Kremlin “does not engage in collecting compromising material”.
