PDJT should read aloud the 1st Amendment as it likely will be the first time for most of the press room.
Secondly, I say to this: Secret Service passes for working White House journalists should never be weaponized.
...well, what of Acosta and CNN weaponizing it against the people and the president, because that is indeed what they are doing with their press pass.
What you suggested should be posted on the outside doors of the press room and inside it in several locations.
Then, maybe have the mediots sign a copy of this, that they have read it and understand it. Then, when they try to Accost anyone, they can be banned.
