The Democrats are trying to remove Trump’s Secret Service protection in case he is convicted of a felony (which is likely to happen in this trial despite the ridiculousness of the charges), but they can’t get that enacted until they get a majority in the House of Representatives. If Merchan orders Trump to jail before the trial is over, he won’t have been convicted of a felony so presumably he would have Secret Service protection (although I’m sure the Democrats will try to find a way to remove it).
We can put absolutely nothing past these demonically driven people. They’re pure Evil.
