The publicity is to scare people into not bringing drugs into the White House.
“But why? This is a White House that has openly invited cross-dressers, queers, pretend-women not only into the White House but into the Administration of our government.”
The Secret Service is trying to maintain the level of legality and professionalism they’d have if Biden was not president. There was a book called, “Absolute Power.” A Secret Service agent covers up an accidental death that happened while the president was having sex with a billionaire’s trophy wife. Next thing you know he’s killing people right and left as one thing leads to another, to another and another. Things just spiral out of control. I think the Secret Service believes that eventually things will be back to normal, and they don’t want to live with the thought they threw away their values just to serve as lackies for an evil man and his court.
