Who's going to stop them? Not their own party. Not even the Republicans will lift a hand to stop this obvious personal vendetta against Trump and his family and associates.
Just like a delinquent child who gets their hand slapped once in a while but who never really gets punished for their bad behavior, the democRATS will keep getting bolder and bolder with their attacks.
There is no pretense anymore. Their agenda is to remove Trump from office by any means necessary.
And if there is no one to stop them, their petty behavior will continue at the country's peril.
There, fixed your sentence...
