"The 'no' was obviously wrong. I corrected it immediately," Giuliani said on Sunday. "What they’re trying to say is I went there for a political mission to kind of get Joe Biden in trouble. Ridiculous. I went there as a lawyer defending his client."

Giuliani continued to insist the coverage should focus on what he claimed were suspicious business dealings involving the former vice president's son Hunter Biden instead of Trump and himself.

"I have all the contacts between Democrats and the Ukraine," Giuliani said. "When the rest of this comes out and we look at China and the $1.5 billion that the Biden family took out of China while that guy was negotiating for us, this will be a lot bigger than Spiro Agnew."

Pressed by Roberts on whether it was appropriate for him to be seeking dirt on Joe Biden while acting as a representative of the president, Giuliani responded, “That’s the way you characterize it.”

“That’s the way it appears to line up,” Roberts replied before Giuliani countered, “That’s the way the pro-Biden media lines it up.”

Despite Giuliani’s repeated implications that the firing of former General Prosecutor of Ukraine Viktor Shokin was politically motivated, Roberts said that he was dismissed amid corruption allegations and that his successor, Yuriy Lutsenko, found no evidence of wrongdoing on Hunter Biden’s part.

“This is going to get bigger and bigger, and everything I say I can prove,” Giuliani said.
