On Saturday the New York Times reported that White House counsel Donald McGahn has "cooperated extensively" with Special Counsel Robert Mueller on the question of whether Trump attempted to obstruct the Russian Federation probe.
"Disgraced and discredited Bob Mueller and his whole group of Angry Democrat Thugs spent over 30 hours with the White House Councel, only with my approval, for purposes of transparency", Trump tweeted, misspelling McGahn's title. His former personal lawyer, Michael Cohen, is mired in accusations he lied to obtain loans for several taxi businesses and arranged payments to women who claimed to have had affairs with Trump, the New York Times reported.
The newspaper also reported that, according to a person with knowledge of the President's thinking, Trump incorrectly thought that McGahn would act as a personal attorney would and exclusively defend the President's interests in interactions with the special counsel team.
Trump views the investigation headed by special counsel Robert Mueller as a stain on his presidency, and has repeatedly pushed for it to be ended.
"So I believe this is a desperate special counsel who leaked this to The New York Times".
At the same time, Burck has cautioned them that McGahn is only one witness and he does not know all the evidence Mueller has gathered that could pose problems for Trump, or how the information McGahn has provided could fit into the broader case.
"From the day I announced, the Times has been Fake News, and with their disgusting new Board Member, it will only get worse!"
Some of Trump's critics have suggested the president, who last week stripped the security clearance of former Central Intelligence Agency director John Brennan and has vowed to pursue similar actions against a list of other critics, is the one who is acting like McCarthy.
On Saturday evening, Mr McGahn's lawyer confirmed the White House counsel had co- operated with Mr Mueller's team. But the Times followed up with another report saying Trump's lawyers do not know how much McGahn told investigators during months of interviews spanning 30 hours.
"I've chose to stay out".
"Where's the Collusion?" Trump tweeted.
Trump lawyer Rudolph W. Giuliani recently told the Wall Street Journal that Trump would not sit for an interview after September 1 because it might interfere with the midterm elections in November.
He added: "But I allowed him and all others to testify - I didn't have to". Once the President's legal team made the decision to waive executive and attorney-client privilege, McGahn had no choice except to cooperate, the source said.
Boston University political analyst Tobe Berkovitz said Trump's claims have merit, calling the comparison of the probe to McCarthyism a "valid point". "And his client is not Donald Trump; his client is the office of the president". I could run it if I want.I'm totally allowed to be involved if I wanted to be.
Mr Trump said later: "Study the late Joseph McCarthy, because we are now in period with Mueller and his gang that make Joseph McCarthy look like a baby!"
"If it's not an idle threat, we are talking about something of the caliber of the Saturday Night Massacre", Vershbow said, referencing President Richard Nixon's mass firing of Justice Department officials at the height of the Watergate scandal.
In an effort to turn lemons into lemonade, Trump has taken credit for permitting McGahn to talk freely to the Mueller team.
