Giuliani also said on NBC's "Meet the Press" on Sunday that Trump pardoning himself is "unthinkable" and "would lead to probably an immediate impeachment". "And he has no need to do it, he's done nothing wrong". He then again decried special counsel Robert Mueller's probe as a "never ending Witch Hunt".
"This morning, the president tweeted that he "has the absolute right to pardon himself" and that "the appointment of the special counsel is totally unconstitutional". "Despite that, we play the game because I, unlike the Democrats, have done nothing wrong!"
Trump's team has sought to discredit special counsel Robert Mueller's investigation into Russian meddling into the 2016 election.
Giuliani has been vocal and aggressive in his defense of Trump on cable news airwaves since Trump appointed him in April as part of his legal defense team. He says the president's legal team hasn't discussed that option, which many observers believe could plunge the nation into a constitutional crisis.
"He has no intention of pardoning himself", Giuliani told ABC's "This Week". "Pardoning other people is one thing".
House Republican Majority leader Kevin McCarthy also told CNN that no president should pardon himself.
Trump's lawyers have been negotiating with Mueller since the end of 2017 over terms of an interview. He said he has informally made the request, but gotten no response.
"I think the political ramifications of that would be tough", Giuliani added. "But look, if they can convince us that it will be brief, it would be to the point, there were five or six points they have to clarify, and with that, we can get this - this long nightmare for the - for the American public over".
A Virginia judge overseeing the trial of former Trump campaign chairman Paul Manafort ordered Mueller's team to turn over the complete three-page memo from August outlining the specific crimes Mueller is authorized to investigate. "If he did, he'd be impeached so fast", Giuliani said. In a controversial tweet earlier this week, Trump touted that he has "absolute" power to pardon himself. The investigation was opened after the emails were hacked from Democratic officials' accounts and published; intelligence officials later formally attributed the breach to Russian Federation.

"We said, 'Well, we're not going to have a summit under those circumstances, '" Mr Giuliani said.
"It seems like it would be a completely wrong assumption".
Giuliani has become a lightning rod during his tenure on Trump's team, drawing the president's ire for a series of scattershot interviews.
"I am even more convinced that the Federal Bureau of Investigation did exactly what my fellow citizens would want them to do when they got the information they got, and that it has nothing to do with Donald Trump", Gowdy said after the briefing last month.
"It is pointing out that the president is the stronger figure", Giuliani told the AP.
He continued: "I think that what Rudy has done is a shame and a disgrace as a former US attorney, and as a former justice official, he knows better, and it's an outright lie".
He also dismissed the conversation surrounding the question of a potential presidential pardoning as "nothing more than an academic debate".
