You are correct. The prosecutor only needs to present enough to get an indictment. But Bragg is getting too cute by half here. Now that it is known that he has withheld hundreds of documents that are favorable to Trump, that information will get to the GJ. It might not dissuade enough of them from indicting trump, but it could change a few minds. I honestly think fat ass knows he’s riding the dragon and he could fall at any moment.
Pomeranz (former prosecutor in manhattan DA office) supposedly wrote a best-selling book complaining about not charging Trump, that embarrassed Bragg into the current GJ project.
