No other government on Earth allows press reporters to office in their Executive Mansion or Presidential offices.
And no other military or intel community would ever allow them to.
China’s useful idiots - they done even have security clearances - otherwise known as the White House Press Corps, office 30 feet from the president, 5 feet from the War Room AND ORDER THE PRESIDENT AND HIS STAFF AROUND LIKE SUBORDINATES.
The press hallway and offices should be turned back into a West Wing hallway and they shouldn’t hold any press conferences unless they warrant forethought and one of the state rooms.
There shouldn’t be any preferred reporters, dedicated space or entitled seating. Invite 100 reporters to a large room or it isn’t important enough to even hold.
Compare the US arrangement to other countries and frame it in terms of security and justify the changes that way.
Remodel the whole hall over a holiday or presidential trip. And then let them know afterwards that there is no longer any dedicated space nor any such thing as a permanent press pass.
