Giuliani started his attacks on the Obama White House and Hillary Clinton’s 2016 campaign. He denied ever courting the theory that Ukrainians hacked the Democratic National Committee and then framed the Russian government. Pivoting, he said there was still “a load of evidence that Ukrainians created false information” for the Obama White House. He also alleged “the collusion that they claim happened in Russia happened in the Ukraine with Hillary Clinton."

“The Ukrainians came to me,” Giuliani said. “I didn't go to them.”

Giuliani has previously called for Ukraine to investigate to determine if Biden — while he was vice president — threatened to withhold monetary aid for Ukraine and pushed for the firing of a Ukrainian prosecutor in order to help his son, Hunter Biden, who held a board position on a Ukrainian energy company. Giuliani has been at the center of the controversy over Trump’s July 25th phone call with President Volodymyr Zelensky of Ukraine in which Trump discussed a possible investigation of the Bidens.

If Trump hadn't asked Ukraine to investigate Biden in his July 25 phone call, Giuliani said Sunday, “He would have violated the Article II, Section 3 of the Constitution.”

The Bidens have long denied wrongdoing, and the vice president’s backers have argued that Biden was pressuring Ukraine’s government as part of an international campaign against corruption. But Giuliani brought allegations of corruption against the Biden to the forefront again Sunday, adding that they received at least $1 billion from China and their work there should be further looked into.

Throughout the interview, Giuliani and host Goerge Stephanopoulos had fiery back-and-forths, disagreeing about media partisanship and the factual accuracy of some of Giuliani's claims.

Heard from Giuliani: “Let’s get on to the point.” “Let me finish.” “George, is it possible for you to ever treat a charge against a Democrat in the same way you treat a charge against a Republican?”

Heard from Stephanopoulos: “Do you accept that’s not true?” “Are you telling me if there was evidence that Barack Obama was calling up the Russians saying, 'I want you to look into Donald Trump,' that you wouldn’t be blowing that up?”

In a testy end to the interview, Giuliani said he might not cooperate with the House Intelligence Committee, at least until Democrats removed chairman Adam Schiff and put in someone “neutral.”

“I have to be guided by my client. If he wants me to testify, I'll testify,” he said, referring to the president. “Adam, where's the evidence? Ask him to produce the evidence.”

Stephanopoulos said, “He's coming up —”

Giuliani cut him off: “Are you going to interrupt him as often as you did me?”
