WASHINGTON, May 27 (Reuters) – Republican US Senator Jeff Flake, who has not ruled out a candidacy against Donald Trump for the White House, criticized Sunday's unsubstantiated assertion as a "distraction tactic" on Sunday FBI's comments on NBC's "Meet the Press" brought him back to the forefront of the few republican MPs who were willing to challenge Trump over his attacks on law enforcement officers who deal with Russians, interfering in the US election 2016 and possible Trump campaign collusion
Investigations started by the FBI in July 201
Flake said that Trump's unfounded allegations about the FBI spying on his campaign, which the President called "Spygate" In the US Senate, the president could try to stop the investigation by shooting Deputy Attorney General Rod Rosenstein for Mueller or the person who appointed him
"The president had this diversionary tactic obviously with the so-called Spygate. "Flake said last week about Trump's claims. "There are concerns that the president is laying the groundwork to continue with Bob Mueller or Rosenstein, and if that did happen, it would naturally cause a constitutional crisis."
Some high-profile Republicans, including Flake, have received similar warnings in recent weeks aired as the Mueller investigation continues and is frequently denounced by Trump.
Mueller is also investigating a possible obstruction of justice by Trump. Trump and the White House have repeatedly denied any deal through the campaign or any other misconduct.
The White House has also said it does not consider dismissing Muller.
In a tweet on Sunday, Trump called the investigation "The Damned Russia Collusion Witch Hunt" – repeating his often expressed resentment about the probe that has tarnished his presidency.
After Trump has called for an investigation into his "espionage" claim, current FBI director Christopher Wray and Rosenstein, who oversees Mueller 's probe. On Thursday he held two secret briefings for senior MPs from both parties on the subject.
Among the subjects counted the democratic MP Adam ship. On Sunday, in ABC's "This Week," he said, "There's no evidence to support this espionage theory, it's just a piece of propaganda that the president wants to proclaim and repeat."
Republican Senator Marco Rubio told the party same program that he has so far found no evidence for the President's allegations about a "spy" of the campaign  "What I've seen so far is an FBI effort to learn more about individuals who come up with the bragging rights Bragging about connections to Russia that pre-empt the campaign, if those people were to work near my office or my campaign, I would want them investigated, "said Rubio, who unsuccessfully trumped Trump in the 2016 Republican presidential campaign.
"If it proves otherwise, it would like to know, but it's up to the FBI to investigate counterintelligence," said Rubio.
U.S. Intelligence agencies concluded in January 2017 that Russian President Vladimir Putin had made an attempt to interfere in the US election by trying to get Trump to victory. Moscow has rejected the indictment.
Flake made a sharp attack on the president when he announced last October that he would not be re-elected to the Senate this year. When asked if he would run for the White House in 2020, he said, "It's not in my plans, but I have not excluded anything, I hope that someone other than the President runs on the Republican side, the Republicans only Remember what conservatism is and what Republicans traditionally stand for.
