Ukrainian Foreign Minister Vadym Prystaiko denied reports that President Trump pressured Ukrainian leader Volodymyr Zelensky during a July phone call that is reportedly the subject of a whistleblower complaint.

According to recent reports, the president repeatedly urged Zelensky to investigate 2020 Democratic front-runner Joe Biden's son's ties to an energy company owned by a Ukrainian oligarch when the two spoke over the phone this summer. The call reportedly prompted an intelligence community whistleblower complaint that House Democrats are currently trying to get their hands on.

Prystaiko, however, dismissed the claims in a Saturday interview, saying, "I know what the conversation was about, and I think there was no pressure. This conversation was long, friendly, and it touched on many questions, sometimes requiring serious answers."

President Trump has also denied any wrongdoing on his part, pointing instead to Biden's threat to withhold $1 billion in U.S. loan guarantees if Ukraine did not fire its top prosecutor, who had been investigating the oligarch who owned the energy company for which his son was a board member, while he was still vice president.

On Saturday, Biden rejected the notion that he had pressured the Ukrainian government on behalf of his lobbyist son. Instead, he called for an investigation into Trump's conversation with the Ukrainian president and doubled down on his demand for Trump to release the transcript of the call.

So far, acting Director of National Intelligence Joseph Maguire has refused to release the contents of the whistleblower complaint to Congress. He is expected to testify before House and Senate intelligence panels next week.
