I still stand by Trump hurt himself by not testifying. Had he charmed and directly answered questions, he likely would have done himself a favor. But alas, after a lot of blustering, he didn’t.
The 12 jurors were mad at Trump for defeating Hillary in 2016 and wanted their revenge. He couldn’t have charmed them, and if he had testified Bragg would have discovered some inaccuracy, however trivial, to charge him with perjury. Trump wanted to testify but his lawyers were able to talk him out of it.
