Trump later added that the "appointment of the Special Councel is totally UNCONSTITUTIONAL! Despite that, we play the game because I, unlike the Democrats, have done nothing wrong!"
Trump's legal team is making clear that it will combat any effort to force the president to testify in front of a grand jury. Giuliani on Sunday underscored one of the main arguments in a newly unveiled letter sent by Trump's lawyers to Mueller back in January: A president can't be given a grand jury subpoena as part of the investigation into foreign meddling in the 2016 election.
But Giuliani, in a series of television interviews, broke with one of their bolder arguments in the letter that a president could not have committed obstruction of justice because he has ultimate authority over any federal investigation.
Yet the former New York City mayor, who was not on the legal team when the letter was written, added that Trump "probably does" have the power to pardon himself, an assertion challenged by legal scholars. He says the president's legal team hasn't discussed that option, which many observers believe could plunge the nation into a constitutional crisis.
"I think the political ramifications would be tough," Giuliani told ABC's This Week. ''Pardoning other people is one thing, pardoning yourself is tough."
Trump has issued two unrelated pardons in recent days and discussed others, a move that has been interpreted as a possible signal to allies ensnared in the Russia probe.
The letter is dated January 29 and addressed to Mueller from John Dowd, a Trump lawyer who has since resigned from the legal team. Mueller has requested an interview with the president to determine whether he had criminal intent to obstruct the investigation into his associates' possible links to Russia's election interference.
Giuliani said on Sunday that a decision about an interview would not be made until after Trump's summit with North Korean leader Kim Jong Un on June 12 in Singapore, and he cast doubt that it would occur at all.
"I mean, we're leaning toward not," Giuliani told ABC. "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."
In addition to the legal battles, Trump's team and allies have waged a public relations campaign against Mueller and the Justice Department to discredit the investigation and soften the impact of the special counsel's potential findings. Giuliani said last week that the special counsel probe may be an "entirely illegitimate investigation" and need to be curtailed because, in his estimation, it was based on inappropriately obtained information from an informant and Comey's memos.
In reality, the FBI began a counterintelligence investigation in July 2016 to determine if Trump campaign associates were coordinating with Russia to tip the election. The investigation was opened after the hacking of Democratic emails that intelligence officials later formally attributed to Russia.
Trump's team has requested a briefing about the informant, but Giuliani said that the president would not order the Justice Department to comply because it would negatively affect public opinion. But he continued to cast doubt on the special counsel's eventual findings, suggesting that Trump has already offered explanations for the matters being investigated and that the special counsel was biased against the president.
"For every one of these things he did, we can write out five reasons why he did it," Giuliani said. "If four of them are completely innocent and one of them is your assumption that it's a guilty motive, which (Trump) would deny, you can't possibly prosecute him."
Trump's legal team has long pushed the special counsel to narrow the scope of its interview. Giuliani also suggested that Trump's lawyers had been incorrect when they denied that the president was involved with the letter that offered an explanation for Donald Trump Jr.'s 2016 Trump Tower meeting with Russians who offered damaging information on Democrat Hillary Clinton.
"This is the reason you don't let the president testify," Giuliani told ABC. "Our recollection keeps changing, or we're not even asked a question and somebody makes an assumption."
If Trump does not consent to an interview, Mueller will have to decide whether to go forward with a historic grand jury subpoena. His team raised the possibility in March of subpoenaing the president, but it is not clear if it is still under active consideration.
A court battle is likely if Trump's team argues that the president can't be forced to answer questions or be charged with obstruction of justice. President Bill Clinton was charged with obstruction in 1998 by the House of Representatives as part of his impeachment trial. And one of the articles of impeachment prepared against President Richard Nixon in 1974 was for obstruction.
