Audio of Russian radio comedians prank-calling Rep. Adam Schiff shows the ranking Democrat on the House Intelligence Committee asking for details about naked photos of President Donald Trump they were offering.

The audio from last year was posted by U.K. outlet The Daily Mail. The audio’s existence was first reported by the Atlantic.

On the recording, the comedians, nicknamed “Vovan” and “Lexus,” pretend to be Andriy Parubiy, speaker of the Ukrainian Parliament. The two have duped a number of celebrities and politicians, including U.N. Ambassador Nikki Haley, with their calls.

The two tell the California Democrat they have evidence that the Russian government has naked photos of Trump.

The photos stemmed from an affair Trump supposedly had with Russian model Olga Buzova, the two comedians say.
