Let's try to navigate through this Beltway Hall of Mirrors.
McGahn has reportedly spent 30 hours being interviewed by Mueller's investigators, providing them with what was described as information that never would have been obtained otherwise.
President Trump's lawyers do not know just how much the White House counsel, Donald F. McGahn II, told the special counsel's investigators during months of interviews, a lapse that has contributed to a growing recognition that an early strategy of full cooperation with the inquiry was a potentially damaging mistake.
The weekend Twitter ire of the president was prompted by the publication of a New York Times piece on White House lawyer Donald McGahn's extensive cooperation in Mueller's investigation based on sources.
Giuliani said during "Meet the Press" that Trump didn't raise executive privilege or attorney-client privilege during those interviews because his team believed - he says now, wrongly - that fully participating would be the fastest way to bring the investigation to a close. No Collusion, No Obstruction. McGahn was a strong witness for the President according to Burck and debriefs of DM (Donald McGahn).
Trump, meanwhile, appears to have mistakenly believed that McGahn would act as his personal attorney who would defend the president's interests.
Trump also claimed, without evidence, that several members of the media had called him to "complain and apologize" and compared Mueller's investigation to Sen. The former White House speechwriter said they visited to deliver a "stand-alone, academic talk titled 'The Intelligentsia and the Right.' I said nothing objectionable and stand by my remarks completely".
Dean was White House counsel to Richard Nixon during Watergate, but ultimately cooperated with prosecutors.
In his Twitter rant, Trump went 20 years back in time from Watergate, to the "red scare" of the 1950s.
In 2016, USA intelligence agencies concluded that Russian Federation had used a state-authorised campaign of cyber attacks and fake news stories planted on social media in an attempt to turn the election against Hillary Clinton. "So bad for America!"
The New York Times said in its report that it was rare for a lawyer to be so open with investigators, but he may have been motivated out of fear of prosecution over White House decisions that might have been construed as obstructing justice.
On Sunday, he compared Mueller with 1950s-era U.S. senator Joseph McCarthy, whose anti-Communist crusade eventually led to his censure by the Senate.
Dean tweeted a reply, saying he had "trouble using the title Mr President for someone installed by Putin".
During this time, he gave "a clear view of the president's most intimate moments with his lawyer", sharing information the paper says investigators would not have previously known about.
Trump compared Mueller's investigation to the tactics employed by the late senator Joseph McCarthy, who alleged that Communist agents and Soviet spies had infiltrated the USA government, accusing some of treason without evidence.
