Republicans have largely stood behind Donald Trump in the first months of his presidency as the FBI and congressional investigations into Russia's election meddling intensified. "There was no collusion between my campaign and any foreign entity".
Mr Trump has been under fire since news emerged this week that he had shared secrets with the Russians and allegedly tried to stop former Federal Bureau of Investigation director James Comey from investigating his former adviser Michael Flynn.
"If I were Mr. Mueller I would jealously guard the witness pool", Graham said. John McCain, R-Ariz., said Trump would be making a mistake to start a rhetorical war with the new investigator. "And numerous questions he declined to answer came down to his concern of whether he might interfere with the investigation by Robert Mueller".
The White House pointed to Rosenstein's memo last week as justification for Trump's abrupt decision to dismiss Comey. He further claimed to have fired Mr Comey after deciding that the basis of the FBI's investigation into his possible ties to Russian Federation was a "made-up story".
The show's hosts said that during those investigations, there were no calls for impeachment or special counsels. "Believe me. My total priority is the United States of America", Trump said.More news: UK's May promises voters immigration curbs, fairer society

At a press conference later on Thursday, Trump said, "I respect the move but the entire thing is a witch hunt".
"If there is obstruction of justice, perjury or false statements made in connection with that investigation", Zeidenberg said. Trump tweeted Thursday morning.
Mr Mueller's broad mandate gives him not only oversight of the Russian Federation probe, but also "any matters that arose or may arise directly from the investigation".
The President's adoption of the role of a victim has been a potent political weapon before and he has frequently used it to position himself against the Washington establishment, including the media which he uses as a foil in the absence of an easily identifiable political enemy, like Hillary Clinton.
The American leader is also denying he told his former FBI director to back off an investigation into since fired General Michael Flynn, who had been his national security adviser.
