On May 3rd, 2017, Then director of the FBI, James Comey, testified before the Senate Judiciary Committee. During this hearing, Comey was asked specifically about being told to stop an investigation. He made it clear that "in his experience" he'd never been told to end an investigation because "It would have been a big deal". He made a clear distinction between voicing an opinion that an investigation is a waste of time versus told to end one. This was under oath with the penalty of perjury if he was lying.
