But GOP lawmakers have grown increasingly anxious since Trump fired Comey, who had been leading the bureau's probe - and after Comey associates said he had notes from a meeting in which Trump asked him to shut down the investigation into the Russian Federation ties of former National Security Adviser Michael Flynn.
The quotes from Trump come from a White House document based on notes taken from a meeting Trump had with Russian Foreign Minister Sergey Lavrov and Russian Ambassador Sergey Kislyak in the Oval Office, according to the New York Times. "None of us, no matter what our political leanings are, no matter how we feel about Trump, feel this is not good for America", McCain said.
President Trump fired FBI Director James Comey.
Trump and the White House have offered multiple, inconsistent motivations for Comey's early dismissal.
The recently sacked intelligence official has agreed to the hearing amid growing concern over President Trump's ties to Russian Federation and his involvement in the ongoing the investigation into former National Security advisor Michael Flynn.
Pressure is mounting in Congress - especially among Republicans - to scrutinize Mr. Trump's investigation in light of the rapid-fire sequences of events taking place since Comey's firing more than a week ago. Sessions has recused himself from the Trump-Russia probe, citing his close involvement in the Trump campaign previous year.
"It's now considered a criminal investigation", said Sen.
"The Committee looks forward to receiving testimony from the former Director on his role in the development of the Intelligence Community Assessment on Russian interference in the 2016 U.S. elections, and I am hopeful that he will clarify for the American people recent events that have been broadly reported in the media", Intelligence Committee Chairman Richard Burr, R-N.C., said in a statement released Friday evening.
The Justice Department on Wednesday appointed former FBI director Robert Mueller to lead the investigation.
When he announced Mueller's appointment this week, Rosenstein said Mueller will have "all appropriate resources to conduct a thorough and complete investigation".
Deputy Attorney General Rod Rosenstein on Friday also stood by a memo he wrote castigating Comey's handling of the Hillary Clinton email probe.
While some Republicans were skeptical about what was essentially a report about part of a memo about a conversation, some anti-Trump Republican lawmakers pounced. Sen.
President Donald Trump is denying that his campaign collaborated with Russian Federation or that he tried to kill an Federal Bureau of Investigation probe of the issue.
He says that even his "enemies" recognize his innocence, and he's declaring himself the most unfairly hounded president in history.
The developments were a blow to White House efforts to dampen down interest in the Russian Federation investigation as Mr Trump and his staff boarded Air Force One for Saudi Arabia, the first stop on his first foreign trip as President.
