To me it wasn't just about the money to be made though. She is in PR. She proved she was good at her job. I would guess that was worth it's weight in gold to her business.
Wether it technically makes sense or not, it doesn't sit well.
The go fund me being in her business name. Not his, or even, her own name. Her ensuring she, and her business, was front and centre. Them now making money from it. Her using him as the ultimate business presentation etc.
It was obvious her kids would start appearing places, the minute she dragged them on TV mid interview while they looked uncomfortable and just said some pre rehearsed words.
The holiday was a bad idea. But anyone who pointed it out were accused of being awful and denying an old man a holiday. Anyone who pointed out that she was spinning a business opportunity were called misogynist, nasty, miserable etc.
But ultimately, she proved she was good at PR and raised a hell or a lot of money. There could be issues if they less that transparent going forward. I would have thought, she would have anticipated that.
If not, the whole thing could backfire, which she will be aware of. I would be surprised if there is anything less than a full & transparent response. I am surprised, though, she didn't ensure there was impartiality.
