We are now in Nixonian territory.

President Donald Trump asked the FBI director, James B. Comey, to shut down the federal investigation into Trump’s former national security adviser, Michael T. Flynn, in an Oval Office meeting in February, according to a memo that Comey wrote shortly after the meeting.

And this from SF Gate:

Comey wrote the memo detailing his conversation with the president immediately after the meeting, which took place the day after Flynn resigned, according to two people who read the memo. The memo was part of a paper trail Comey created documenting what he perceived as the president’s improper efforts to influence an ongoing investigation. An FBI agent’s contemporaneous notes are widely held up in court as credible evidence of conversations.
