Donald Trump took to Twitter on Saturday, suggesting that Special Counsel Robert Mueller, who oversees the probe, is QUOTE-deliberately leaking documents to the press. If Trump refuses that request, Mueller will have to decide whether to pursue a grand jury subpoena of the president.
US President Donald Trump's lawyers have composed a secret 20-page letter to special counsel Robert Mueller to assert that Mr Trump can not be forced to testify in the ongoing investigation into Russian meddling in the 2016 election. "He also has Constitutional authority to direct the Justice Department to open or close an investigation, and, of course, the power to pardon any person before, during, or after an investigation and/or conviction".
In the letters, Trump's lawyers sternly oppose attempts by Mueller's office to interview him, saying "under our system of government, the president is not readily available to be interviewed".
Though it is written as a defense of the president, the letter recalls the tangled drama of early 2017 as the new administration dealt with the Russian Federation investigation.
"In light of these voluntary offerings, your office clearly lacks the requisite need to personally interview the President", the letter argues.
"There was No Collusion with Russian Federation (except by the Democrats)", Trump tweeted shortly before the Times story was published. "So bad for our Country", he tweeted. "Should be looking at Dems corruption instead?"
A conservative activist believes if Jeff Sessions had told President Trump that he would recuse himself from any "Russia collusion" probe, the president could have picked someone else to be his attorney general.
They also spelled out in detail why the firing of James Comey, the Federal Bureau of Investigation director, and other key moments being scrutinised do not amount to obstruction of justice.
Kasowitz also said an interview with NBC's Lester Holt was taken out of context when Trump said, "I was going to fire Comey knowing there was no good time to do it".
One legal expert consulted by the Times said, "it is not clear whether statutes criminalizing obstruction of justice apply to the president and amount to another legal limit on how he may wield his powers".
They argued that the president holds a special position in the government and is busy running the country, making it hard for him to prepare and sit for an interview.
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.
