I wouldn't know him from Adam, nor does it make any fucking difference. If/when charges are brought against Trump, they'll come from the DoJ. Whine about the moderate centrist Garland all you want, the evidence will speak for itself during trial.
It's just one of those connect the dots type of deals. The circumstances surrounding Epstein's murder were extremely suspicious, and the only people with the access to both make the security guards and cameras disappear for the night would've been Trump and Barr. Maxwell is a lower-level crony, plus she never had to be in a prison overseen by Barr.
Oh we already know that Trump was in Epstein's black book, along with a lot of other rich and politically connected folk.
