After the meeting, Comey immediately wrote a memorandum describing what Trump had said, and gave copies to Baker and his other senior staff. Comey was again shocked by Trump’s behavior. The president was asking the director of the FBI to drop a criminal investigation of a close aide. Worse, the aide had lied to FBI agents about his contacts with Russia, a foreign power that had intervened in the election to help Trump. The behavior smacked of a cover-up.
