In a macro sense, does it even matter that Trump will produce more evidence for the prosecution at his press conference? As I see it Smith and Willis already have him dead to rights and he and the coup plotters are more focused on a post-conviction strategy that is based primarily on winning or a stollen election. As well as a hail mary play to get some MAGAts on the juries somehow such that the actual lawyering and evidence don't matter.
In Trump's calculus, more media spotlight, lathering up the base electorally and insurrectionally, and assaulting confidence in our institutions is significantly more valuable than the downside of adding to Jack Smith's mountain of evidence.
His attorneys are just whining because it makes an already impossible job harder but they have no ability to change the course that has long been charted. They are there just to bill and try not go to jail...and place their early bets to become the next Prigozhin in emperor Trump's America.
