“Details such as Ivanka moving her family to Moscow to manage a spa in the hotel.”
This was what immediately spotlighted how false the story must be. I have a daughter who lived in Moscow for several months - quite an experience she has no desire to repeat. There is no way anyone in the Trump family would move there. Visit for a short period, ok, but not move there.
If you're a billionaire businessman, Moscow is where you send your kid who's always in trouble and can't stay out of the tabloids. Ivanka was managing a multimillion dollar fashion brand at the time (before liberals essentially devalued it by forcing it off the shelves). I can't exactly imagine her father saying, "Pack it up sweetie! You've got a spa to manage! And you might want to buy a shapka. It's gets cold where I'm sending you!"
