I'm waiting for more info and happenings, but it's possible that Schumer was trying to avoid the shutdown (and the subsequent arrests) and Trump compelled him to do it by literally scaring the shit out of him.
Who made the plan?
More than 30 million. All independent real people following their conscience. If Brock wasn't a gay psychopath he would understand that when you are a handful of people being paid and you go up against that, you are the bad guys.
