Typically, blackmail involves a money payout but I think Comey was using it to pressure Trump.
The “Golden Shower” story was already leaked before the election and I believe the intent was to inflame black voters to turn out for Hillary (and perhaps turn off some fundamentalists).
Otherwise, who cares? Was it illegal? Regardless, it never happened. They couldn’t even prove he was in Russia for this incident to have happened.
These fools ,despite being the top cops at the FBI and CIA and director of national intelligence , were complete fools and complete losers who have no idea how to pressure anybody
Our great and wonderful president Donald J Trump has been dealing with mafia bosses his entire life running construction projects in New York City did make all these little pipsqueaks look like complete pikers
