Sworn Donald Trump enemy John McCain admitted Wednesday that he passed the dossier of claims of a Russian blackmail plot against the president-elect - calling it 'what any citizen should do'.
McCain - a longstanding anti-Trump Republican who had disassociated himself from the candidate's campaign weeks before the election - cast himself as an innocent and concerned member of the public as he justified his move.
He claimed he had no idea whether it was accurate or not - but that he believed the FBI should have it because it was 'sensitive'.
'I did what any citizen should do. I received sensitive information and handed it to the FBI,' he told CNN - the network which broke the story that the document existed. It was then published in full by Buzzfeed.
'That's why I gave it to the FBI. I don't know if it is credible or not but the information I thought deserved to be delivered to the FBI, the appropriate agency of government.'
He added: 'It doesn't trouble me because I don't know if it is accurate or not. I have no way of corroborating that.
'The individual gave me the information. I looked at it. After receiving that information I took it to the FBI.'
