He prob didn’t know SDNY was moving on Epstein.. SDNY is largely independent and the US AG don’t have the clout like that to interfere with its investigations..
SDNY is the Feds, meaning Trump can pardon Epstein of crimes. Is anyone gonna pardon a dude accused of child sex trafficking? Probably not, it would be suicide lmao. But Trump is Trump, and may be implicated so you never know. Before we even get to that point, the evidence presented would seal Trump's fate IF he's actually guilty. I expect nothing so I'm not making predictions...outside of that Bill Clinton and Dershowitz are probably fukked.
SDNY hasn't really leaked shyt. They've been investigating Cohen, they've taken down Manafort, etc. Trump's inability to get an "inside man" in there has probably kept him up at night all year.
