His own lawyers have already proved he lied, when they sent the prosecution the entire contents of his phone and refused to claim anything as privileged when prompted on it.
Edit: then there's the fact that he continually held press conferences outside the court house and court ROOM despite being told NOT TO by the judge due to the presence of jurors. He's literally flaunting the entirety of the rule of law, and openly mocking the system. I'm honestly surprised he hasn't been held in contempt again.
