News reports I've heard indicate the unindicted co-conspirator is not 45 himself but Trump Org Senior VP and Controller Jeff McConney, who provided info to the grand jury that continues to meet and will certainly be bringing more indictments in coming months.
These charges are quite serious, the kind of crimes that people do hard time for. The case for all of them is a slam dunk--extra set of books leaves no room for misinterpretation--and forces Weisselberg to think about what years in prison would be like at his age. Will he take the fall for 45? And will it help the former "president," even if he does? Stay tuned.
