Suggestion 1:
At the next press conference, have a decibel meter in the briefing room. Before the press conference begins, explain that if the meter hits over a certain level, the meeting will immediately stop. With Jimmy the Accoster at the next press conference, PDJT should ignore him, letting him raise his voice until he goes over the decibel level. Immediately end the press conference, explaining exactly why it was stopped. This happens a few times and the press
corp corpse will start blaming and attacking the Accoster.
Suggestion 2:
Install a sophisticated sound system in the press room that records Jimmy the Accoster and plays it back at 1/2 cycle delay. That should cancel most sound coming from him. Just to make things more fun, have a system that changes his voice to sound like he is speaking after breathing helium. THAT should shut him up.
