Christopher Steele doubled-down on claims from his infamous dossier, insisting that Michael Cohen met with Russian officials in Prague and that the 'golden showers' tape of Donald Trump likely exists.

In his first major interview, which is set to come out on Hulu on Monday, Steele told ABC's George Stephanopoulos that he is speaking out because 'problems we identified back in 2016 haven't gone away – and arguably have actually gotten worse.'

During previews of the interview shared on ABC This Week on Sunday, Steele defended his dossier against criticism and contradictions coming from the FBI and other probes into claims made in the bombshell opposition research document.

'Today do you still believe that that tape exists?' Stephanopoulos asked in reference to the salacious 'golden showers' tape claimed to exist in the dossier that has never come to light.

'I think that it probably does, but I wouldn't put 100 per cent certainty on it,' he said.

'So how do you explain if that tape does indeed exist, why hasn't it been released?' the ABC reporter pushed.

'Well it hasn't needed to be released?'

'Why not?'

'Because I think the Russians felt they got pretty good value out of Donald Trump when he was president of the U.S.,' he said.

The tape in question is a claim in the Steele dossier that alleged Trump hired prostitutes in 2013 during a trip to Moscow and paid them to perform 'golden showers' or urination in front of him on the bed at the Ritz-Carlton's presidential suite.
