The disgraced financier’s brother
You mean convicted pedophile sex trafficker. Let's not mince words here.
The article does not reveal any actual new facts, only that Mark Epstein agrees with the general public that Trump and Epstein were close, and that Mark thinks he had him killed. No new evidence is provided for this.
So basically this is all a bit of a nothing-burger.
Hardly a "bombshell email".
