He said to Ukrainska Pravda commenting on SBU's claims that Onyshchenko is drafting massive informational attack against Ukraine under a Kremlin-approved strategy, Censor.NET reports.
Onyshchenko noted that SBU's accusations came as a reaction to his interview in which he blames the Poroshenko administration of buying votes in the parliament.
"I have lots of incriminating evidence against Poroshenko. So they will be like 'it's Kremlin's hand'," the MP said.
Several days ago Onyshchenko said he was going to hold a news conference and publish information against the acting government.
Some sources say Onyshchenko has been recording his conversations with the president of Ukraine to his wrist watch over the past year.
"You will hear the voice of the head of state and your illusions of his love to the state and the people will be shattered. I worked with him closely for two years, and know him well," the member of the parliament said.
Answering a question whether he shared this information with anyone, Onyshchenko said: "[I passed it] to the U.S. secret services. They came to see me in Europe," and showed a letter from the Criminal Division of the U.S. Department of Justice.
Ukrainska Pravda reports of good relationship between Onyshchenko and U.S. President-Elect Donald Trump.
