"He's done a lot of work in Ukraine over the years and I think, I mean that's what I heard".
But asked by O'Reilly what Giuliani did on his behalf in Ukraine, Trump said, "I don't even know". But the negotiations proceeded far enough that a series of legal agreements were drafted under which Giuliani's company would have received more than $200,000 to work for the Ukrainians, people familiar with the agreements said.
It wasn't clear if Trump meant to somehow distance himself from Giuliani with his remarks to O'Reilly. One proposal signed by Mr Giuliani in February involved the Ukrainian Ministry of Justice. "I could have helped them recover $7B in stolen money, but I didn't".
The proposed April agreement between Mr. Lutsenko and Ms. Toensing and Mr. diGenova also referenced another assignment: helping the Ukrainians meet with American officials about "the evidence of illegal conduct in Ukraine regarding the United States, for example, interference in the 2016 US elections".
"Secretary Perry, Ambassador Volker and I worked with Mr. Rudy Giuliani on Ukraine matters at the express direction of the president of the United States", Sondland said.
And top diplomats have testified that Giuliani's role loomed large over their own official operations regarding Ukraine.
"But you have to understand, Rudy is a great corruption fighter".
The report comes as President Donald Trump's personal lawyer continues to face questions about his work for Trump following the release of a whistleblower complaint at the center of impeachment proceedings involving the President and Ukraine.
He said there had been no change in Trump and Giuliani's relationship.
In response to the report, Giuliani told the outlet, "This is attorney-client privilege, so I will withstand whatever malicious lies or spin you put on it".
"And because he has no defense on the merits, it may very well be that at some point, Katy, he's going to have to say, 'You know what?"
Prosecutors alleged Parnas and Fruman used foreign money to buy political influence in the US, directing large donations to USA politicians as they "sought to advance their personal and financial interests and the political interests of at least one Ukrainian government official with whom they were working". But if there's nothing there I'll be the first one to say there's nothing there.
After news broke in May of a trip Giuliani planned to take to Ukraine, the lawyer told The New York Times that the president "basically knows what I'm doing, sure, as his lawyer."
Federal prosecutors in the U.S. have been investigating Giuliani and two of his associates, Lev Parnas and Igor Fruman, for wire fraud and failing to register as a foreign agent, The Post reported.
Two of Giuliani's associates, Lev Parnas and Igor Fruman, were charged with funneling money from foreign entities to USA candidates to buy influence.
A lawyer for Andrew Favorov confirmed Tuesday that he is scheduled to meet voluntarily with the U.S. Justice Department.
