POTUS No. 45 is getting an object lesson on a fact of life, which is that he cannot control every single environment.

I haven’t been following this hush money trial too closely, but I have chuckled — sometimes out loud — at the examples of the judge not standing for the shenanigans that the former sexual assailant in chief has tried to pull in the courtroom.

And yesterday, Judge Juan Merchan told Robert Costello, a witness for the defense, to stop staring him down … or else face the consequence that the judge could level on him and the criminal defendant.

The former philanderer in chief is on trial for paying the adult film star known as Stormy Daniels 130 grand to keep quiet about a tumble that he denies occurred. Go figure … yes?

Now his future is in the hands of the judge and the jury impaneled to hear this tawdry case. As to the discomfort he might be feeling because he isn’t in charge of a damn thing, I don’t give a sh**.

The overfed crook will just have to suck it up.
