Prediction - the IG report will not drop until after Comey's book is released April 17.

Use logic.

If Comey is now white hat, then it allows him to drop the redpill first.

If black hat, then it catches him lying bigly.

Curious though about LL and what story she will spin, and whether it will be immediately countered with evidence. Is she going to perjur herself in prime time?
