She was forced to act, because Judge Dearie was being really mean to President Trump, and she's not going to allow that.
He thinks, just because he's been a respected federal judge since she was in kindergarten, that he gets to make President Trump "put up or shut up"! He was overstepping, yeah, that's what! And he was rushing things, when President Trump was in no hurry at all. She doesn't have to put up with that kind of malarkey!
I can't wait until the government tries to indict Trump, and she, oh, I dunno, tries to vacate the indictment or sumpin'.
Trump can't decide if he's really president still or whether the federal government is against him just because he filed a lawsuit called Donald J. Trump vs. United States of America.
But by gum, if he's fighting the government of the United States, he's gonna need some help, and Judge Cannon is there for him.
