Under the pressure of possible treason charges Comey started taking written notes not to harm the president but testify and help negate the lies.
He could be the witness that disproves the entire hoax.
Comey kept the memos out of the FBI storage and safeguarded.
It seems odd to hand-write these memo's but think.
He could not do any of this on a computer phone or digital device! It had to be written down for him to recall events and be a credible witness.
