Trump responded to the news on Saturday, suggesting that people involved in the investigation had leaked the letter to the media.
The special counsel's office has been seeking an interview with Trump as part of its inquiry into possible collusion between his campaign and Russian Federation in 2016, along with potential obstruction of justice on the part of the president. Negotiations between Trump's lawyers and the special counsel on a possible interview have continued since. "I would do it under oath".
In the letter penned by Trump lawyers John Dowd and Jay Sekulow, it was argued that President has the power to "order the termination of an investigation by the Justice Department or FBI at any time and for any reason".
"Indeed, the President not only has unfettered statutory and Constitutional authority to terminate the Federal Bureau of Investigation director", the letter states.
"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".
Trump tweeted about the letter ahead of the impending report, repeating the big lie that it was the Democrats who were colluding with Russian Federation ahead of the election, and asking, "When will this very expensive Witch Hunt Hoax ever end?"
He said the investigation was "so bad for our country" and asked: "Is the Special Counsel/Justice Department leaking my lawyers letters to the Fake News Media?" Trump wrote. "Should be looking at Dems corruption instead?"
In a confidential letter obtained by The New York Times, lawyers for President Trump reveal their legal strategy and inform special counsel Robert Mueller that Trump will not comply with requests for an interview.
If Mr Trump does not consent to an interview, Mr Mueller will have to decide whether to forge forward with a historic grand jury subpoena.
For someone who thinks he has "the best words", Donald Trump sure seems to have a hard time spelling them. In April, Trump hired former NY mayor Rudy Giuliani and two other former federal prosecutors to join his legal team.
According to The Hill, there are no indications that Sessions is going to quit or that the president is going to fire him. Our legal team would not disclose internal communications with the office of special counsel.
The letter does not stress legal opinions by the Justice Department in the Nixon and Clinton administrations that held that a sitting president can not be indicted, in part because it would impede his ability to carry out his constitutional responsibilities. Trump's decision to dismiss the FBI director was an appropriate use of presidential power meant to exert oversight over the bureau as a result of its missteps in the 2016 investigation of Hillary Clinton's use of a private email server while she was secretary of state, they wrote.
But if Trump's lawyers were saying it's impossible for a president to obstruct justice because he's the nation's chief law enforcement officer, they went too far.
The legal assertions made in the letter, which constitutional experts say raise novel issues, likely will be tested in court if Trump declines an interview, Mueller issues a subpoena and a legal battle ensues.
