The ranking Democrat on the House Intelligence Committee was the victim of a prank phone call by Russian comedians who offered to give him ‘compromising’ dirt on Donald Trump – including nude photos of the president and a Russian reality show star.

DailyMail.com can disclose that after the prank, his staff engaged in correspondence with what they thought was a Ukrainian politician to try to obtain the ‘classified’ material promised on the call.

On an audio recording of the prank call posted online, Adam Schiff can be heard discussing the committee’s Russia investigation and increasingly bizarre allegations about Trump with a man who claimed to be Andriy Parubiy, the chairman of the Ukrainian Parliament.

The call, made a year ago, was actually from two Russian comedians nicknamed ‘Vovan’ and ‘Lexus’ who have become notorious for their phony calls to high-ranking American officials and celebrities, including UN Ambassador Nikki Haley and Elton John.

Its existence was first reported by The Atlantic but not how a staff member working for the minority on the House Intelligence Committee pursued the information after the call.

Schiff’s office said the congressman suspected the call was ‘bogus’ from the beginning and reported it to authorities afterward.

But in a recording of the eight minute conversation, Schiff appeared to take the call seriously – or at least played along convincingly – and emails from the Democrat’s staff to the fake politician afterwards said he had found it ‘productive’.
