Giuliani agreed with the letter's finding that Trump has unlimited power to pardon while saying, in a separate appearance on NBC's "Meet the Press," that pardoning himself would probably lead to impeachment. "We're leaning toward not", said Giuliani, per Politico.
Giuliani said Trump's lawyers would tell Mueller's team that "you've got everything you need, 1.4 million documents, 28 witnesses" to conclude its investigation.
Giuliani's comments came a day after The New York Times revealed that Trump's lawyers in January made their case to special counsel Robert Mueller that Trump could not possibly have obstructed justice because he has the ability to shut down any investigation at any time.
Meanwhile, former Trump campaign manager Corey Lewandowski told "Fox News Sunday" that President Trump's legal team will "take it to court" if Mueller subpoenas him as part of the Russian Federation probe.
The question of self-pardon arose after the New York Times published a letter to the counsel from Mr Trump's lawyers. Could he self-pardon for "all prior federal crimes", including things like tax evasion, and continue doing so each morning for the rest of his tenure in office?More news: Iran Foreign Affairs Minister Mohammad Javad Zarif arrives in India

That meeting was scheduled after the Russians said they had damaging information about Democratic presidential nominee Hillary Clinton that would be of use to the Trump campaign.
Trump's team not only argues that he can pardon himself but also argues that he has unlimited power to investigate his enemies and end investigations into his friends. That is because, they say, obstruction of justice "would amount to him obstructing himself" as the nation's chief law enforcement officer.
On Sunday Giuliani, by turns, said that conflicting statements about the source of Don Jr's statement were one reason he would not want the president, his client, to grant an interview to Mueller's prosecutors. "If this goes to court, I guess we'll find out". "I think [if] the president decided he was going to pardon himself, I think that's nearly self-executing impeachment", Bharara told CNN's 'State of the Union'. The President has never said he would pardon himself. In other words, even if the president fired Comey (or Mueller) exclusively to protect himself from criminal liability, it's all perfectly legitimate.
Trump's lawyers precede their arguments for why Trump should not be interviewed in regards to Comey's firing by pointing out that the president acted within the authority granted to him by the Constitution. It's wrong. They were trying to make a broad argument.
