Former New York Mayor Rudy Giuliani, who was a lawyer for President Donald Trump, speaks during a news conference at the Republican National Committee headquarters in Washington on Nov. 19, 2020. A law enforcement official tells the Associated Press that federal investigators have executed a search warrant at Rudy Giuliani's Manhattan residence. The former New York City mayor has been under investigation for several years over his business dealings in Ukraine.

Rudy Giuliani, former President Donald Trump’s personal lawyer, repeatedly pressured the Ukrainian government to investigate Democrat Joe Biden over a 40-minute phone call in 2019, according to an audio recording obtained by CNN.

During the call with U.S. diplomat Kurt Volker and Andriy Yermak, a senior adviser to Ukraine President Volodymyr Zelensky, Giuliani can be heard urging an investigation of Biden, who unseated Trump in the 2020 election.

Giuliani said a public announcement would “clear the air really well” and allow for a possible meeting between Zelensky and Trump.

“And I think it would make it possible for me to come and make it possible, I think, for me to talk to the President (Trump) to see what I can do about making sure that whatever misunderstandings are put aside,” Giuliani said on the recording. “I kinda think that this could be a good thing for having a much better relationship.”

Congressional testimony during Trump’s first impeachment detailed how he sought the investigation into the Democratic rival who eventually beat him in the 2020 election.
