It seems Katie Zacharia is out the door after five days on the job. She obviously wasn't cut out for life in the fish bowl. There's a Mark Twain quote which applies to her situation, "Never tell a lie when the truth would do just as well."
She could have come out of the gate saying, "After law school, I decided the life of an attorney wasn't for me," and that would have been the end of the story.
I imagine this snowball from Hell got started rolling when someone in the Trump administration assumed she was a lawyer and she didn't correct them. After all, in the Trump administration, "background check" is a dirty word.
She's young and currently blonde, which is what Trump likes, so there was no reason think she would be worse than any of the previous press secretaries. She stepped into the trap that snares a lot of PR professionals. Instead of telling the story, she became the story.
A smarter person could have avoided all of this, but that's kind of the biography of the entire administration..
