That would be good for Trump. So it won't happen.
The last Dem Primary is June 14: Washington D.C. The FBI will not issue any report to Justice before then.
The Dem Convention starts July 25th. IMHO, the FBI will issue their report and hand it to Loretta Lynch before that date but no sooner than June 15.
What will Lynch do when she gets that report? Easy answer: Request a meeting with Obama.
What will Obama do? Now that is the question isn't it.
