In a series of statements on Twitter Thursday, Trump repeated his assertion that Mueller's investigation into Russian interference in the 2016 campaign is a "WITCH HUNT" based on the "phony" premise of possible collusion between Russia and a cadre of Trump campaign associates. Dianne Feinstein (D-CA), who said she's anxious that the President will try to fire both Mueller and Rosenstein. "That's undemocratic on its face and a blatant violation of the president's oath of office", Feinstein said in a written statement. "Sad!" Trump said in his first tweet of the day.
The move ordered Thursday by the transition's general counsel cast a wide net on documents tied to the Russian Federation investigation as well as inquiries into the activities of Trump associates.
He continued: "Americans should be skeptical about anonymous allegations".
He has decided - after consulting with a small circle of advisers in multiple meetings over the last few days - that "this is a political fight and he's going to fight it", the official said.
According to reports, three of the 13 newly-hired members of Mueller's investigative team have donated to Democrats in the past. What is clear is that he could order the Justice Department to ax Mueller, which may result in Rosenstein's departure and would certainly intensify the uproar over the investigation.
Flynn, who was forced out in February, is a subject in investigations by intelligence committees in the House and Senate, as well as the Federal Bureau of Investigation. Comey said he believes Trump ultimately fired him "because of the Russian Federation investigation".More news: Ronaldo's Real rage genuine or a cunning ploy?

Citing a memo from the general counsel's office of Trump's transition team, the Times said former members were given the order on Thursday for any information involving Russian Federation or Ukraine in the latest sign of the investigations' expanding reach.
ABC News reported that Mr Rosenstein has told colleagues privately that he may have to step aside from the investigation.
Comey last week told the Senate Select Committee on Intelligence that he authorized the leak of the existence of the memorandum through a Columbia law professor and that the reason for the leak was to highlight the need for the appointment of a special prosecutor. However, Trump later asserted that he had already made the decision himself to fire Comey.
That includes information about the activities of Trump associates, including former National Security Advisor Michael Flynn, Trump campaign chairman Paul Manafort, outside adviser Roger Stone and foreign policy aide Carter Page.
The White House has directed questions to outside legal counsel, which has not responded.
A representative for Trump's lawyer promptly reacted to the allegation.
