Comey's caution to meet Trump's tweets in Russian Federation hearing

Comey's written testimony describes several different contacts he had with Trump, including a January 27 dinner where he said the president told him, "I need loyalty".

But if, while fielding questions from lawmakers on the Senate Intelligence Committee, Comey does make a reasonable case that Trump tried to obstruct an investigation into the Russians' meddling in the United States presidential election, then Wall Street's initial muted reaction might turn a little more volatile in the weeks and months ahead. In his seven-page testimony, Comey wrote that he found Trump's intervention "very concerning", reported The Guardian.

The former director of the FBI says President Donald Trump is a liar who improperly directed him to stop investigating a key ally and then fired him in an attempt to affect the broader investigation into the Trump campaign's dealings with Russian Federation.

However, Trump felt "completely and totally vindicated" by the written testimony, his private attorney said, as Comey confirmed he had told the president he was not personally under investigation.

"He said he had nothing to do with Russia, had not been involved with hookers in Russia, and had always assumed he was being recorded when in Russia", said Comey, who had briefed Trump on "salacious material" that had arisen in a counter-intelligence investigation. But once senators began asking their planned post-introduction questions of Comey, there's no telling what will happen.

A few minutes earlier, Manchin had asked Comey: "Do you believe there were any tapes or recordings of your conversations with the president?"

The White House's stated reasons for firing Comey were contradicted by the president himself, raising questions about whether Trump had fired Comey to derail the Russian Federation investigation.

But it's clear that unlike Democrats, who view the hearing as a potential political win, every Republican on the Hill wants the hearing over in order to move onto legislative agenda items.

Comey underlined these points as he answered senators' questions in the almost three-hour hearing Thursday, adding that he took meticulous notes after every interaction with Trump because Comey "was honestly concerned that he might lie about the nature of" their meeting. Even former Trump aides Mike Dubke and Katie Walsh have also been involved in the effort, officials said. And Trump then asked Comey to end the probe into Flynn, according to Comey, who memorialized the meeting right afterward in a memo.

Bruce Green, a professor at Fordham University School of Law, said it would be hard to show Trump meant to impede the Flynn investigation. A president's unprecedented request for loyalty from an Federal Bureau of Investigation director.

Comey related his sense of foreboding when he was asked by Trump to remain behind after after a wider meeting of White House and national security officials in the Oval Office. Asked whether the president stood by earlier assertions that he had neither sought Mr Comey's loyalty nor asked for the Flynn investigation to be dropped, she said: "I can't imagine the president not standing by his own statement".

The White House tapped the Republican National Committee to handle the rapid response to Comey's testimony Thursday, a source familiar with the White House's planning told NBC News yesterday.

He is also likely to be asked why he didn't act sooner given his concerns about the president.

But Comey was not the only one to suggest pressure from Trump.

"Well first of all, let's look at the big constitutional picture", Dershowitz said. Though Comey claimed he chose to put the leak in motion on the evening of May 15, the Times was quoting from the memo as early as May 11 - the day before Trump's tweet.

Thursday's hearing included discussion of that email investigation, as Comey disclosed that then-Attorney General Loretta Lynch instructed him to refer to the issue as a "matter", not an "investigation".
