My take:
Wray set the stage for Trump to declare the KKK and Antifa terrorist organizations. He couldn't declare Antifa a terrorist organization alone. He also threw "lynching" in there for fun.
When is the last time you saw a KKK member perform a lynching in the news?
I think Antifa was the target and Wray played a role. He needed to gain the Democrats' trust and adulations.
