Question: How can this kind of talk even be mentioned in a constitutional republic that has not been usurped by an enemy force? You mean, that a Communist tactic - jailing relatives to destroy someone, is alive and well in the United States?
If they actually do go after Trump's kids to get Trump to resign the presidency, which should be completely impossible, it is more than "game over", it is civil war time. That is beyond an abuse of power, it amounts to an official declaration of war on the United States. "Try as we may, we cannot get you, and we really can't get your kids legally either, but that won't stop us from using corrupted police and corrupted courts to jail them.
This is off the edge, if they pull this crap it is clearly war time.
