U.S. President Donald Trump said Sunday he did nothing wrong in a telephone conversation with the new president of Ukraine amid news report that Trump allegedly urged him to investigate the son of former vice president and 2020 Democratic presidential hopeful Joe Biden.

Speaking to reporters, Trump described his phone call with President Volodymyr Zelensky as "absolutely perfect."

"The conversation I had was largely congratulatory, was largely corruption, all of the corruption taking place. It was largely the fact that we don't want our people, like Vice President Biden and his son creating to the corruption already in the Ukraine," Trump said.

According to news reports, Trump urged Zelensky about eight times during their conversation to investigate Biden's son. Sources were quoted saying Trump's intent was to get Zelensky to collaborate with Trump lawyer Rudolph Giuliani on an investigation that could undermine Biden.

Ukrainian Foreign Minister Vadym Prystaiko on Saturday denied Trump had pressured Zelensky during the call, telling the media outlet Hromadski that Ukraine would not take sides in U.S. politics even if the country was in a position to do so.

Trump and Guiliani have pushed for an investigation of the Bidens for weeks, following news reports this year that explored whether a Ukrainian energy company tried to secure influence in the U.S. by employing Biden's younger son, Hunter.
