Following reports of collusion between Ukrainian government officials and Democratic National Committee (DNC) operatives, a Ukrainian member of Parliament is calling for a criminal investigation into alleged “illegal interference” in the 2016 US presidential election.

Ukranian MP Andrei Derkach requested the meeting in a July 24 letter to Ukraine’s prosecutor general, Politico reported. Derkach claims the alleged meddling has damaged US-Ukraine relations. (RELATED: Everybody Is Forgetting That Clinton Allies Did The Same Thing As Don Jr.)

“Only a transparent and thorough investigation into the unlawful interference of Ukrainian officials with the U.S. election campaign can restore the trust of our strategic partner,” Derkach wrote in the letter, copies of which were obtained by Politico.

Politico reported in January the extent of the DNC’s collaboration with Ukrainian government officials who wanted Democratic nominee Hillary Clinton to win the 2016 election.

A veteran DNC operative who previously worked in the Clinton White House, Alexandra Chalupa, worked with Ukrainian government officials and journalists, both from Ukraine and America, to dig up Russia-related opposition research on Donald Trump and then-campaign chair Paul Manafort. She also shared her anti-Trump research with both the DNC and the Clinton campaign, according to the Politico report.

Derkach wrote in his letter that the “illegal interference” was “organized by a criminal organization” that included senior government officials.
