President Donald Trump flatly denied Thursday that he ever urged ex-FBI Director James Comey to back off or close the investigation into former national security advisor Michael Flynn.

"And he said that ever since, the President had been trying to be chummy in a fashion that Comey felt was created to absorb him into Trump's world - to make him part of the team". Trump later said he had already chose to dismiss him and was thinking of "this Russian Federation thing". That's according to the panel's chairman, Republican Sen.
