Giuliani told ABC News, "If they do, we'll see what happens when we enforce it."
Giuliani went on to say that he no longer avails himself of the services of Jon Sale, who acted as his lawyer in this matter. Giuliani said that if Congress wants to force a subpoena, he will keep the lawyer.
As part of his last official acts as his lawyer, Sale sent a letter to Congress on Tuesday answering the summons that Giuliani had sent.
Tuesday was the deadline for Giuliani to meet a sweeping subpoena of three House committees working on the increasing impeachment investigation against President Trump Jerry Nadler and Elijah Cummings said Giuliani had "admitted on national television that he had the called on the Ukrainian government, as the president's personal advocate, to attack former vice-president Joe Biden. "
The president, his agent Rudy Giuliani and others have apparently urged the Ukrainian government to carry out two politically motivated investigations, "wrote the Democratic chairmen. "The committees have reason to believe that you have information and documents relevant to these matters."
Giuliani had previously spoken to ABC News Chief Anchor George Stephanopoulos, who would consider cooperation with the motion of the Congress, but only if his client, President Trump, gives his consent.
"I'm a lawyer, it's his privilege, not mine," Giuliani told ABC News last month. "If he decides to testify, of course I'll testify, even though I think Adam Schiff is an illegitimate chairman, and he's already anticipated the case."
Giuliani has emerged as a central figure in the investigation. Citing the recent testimony, the Democrats accuse Giuliani of carrying out a shadow operation on foreign policy for the benefit of the Trump campaign. Two Ukrainian-American businessmen who reportedly helped Giuliani investigate Trump's political rival, Joe Biden, and Biden's son Hunter, were charged last week with allegations of campaign funding.
Guiliani's business continues to be the subject of ongoing criminal investigation by the federal authorities in New York.
