Trump's coy response was a must do. Imagine what Diddy's attorneys could do with any declaration on the case by the President. I remember Nixon did this once in a case that everyone considered obvious and courtroom hell broke out. Trump has to remain neutral.

My thoughts exactly.

Reading the transcript, Trump has to take a neutral and impartial stance on this.

Trump probably knows Diddy is guilty and so do his aides and advisors, but they are probably keeping their mouths relatively shut to avoid saying anything that can or might compromise the case against Diddy.
