Trump didn’t hire someone with skeletons in his closet. Acosta was specifically asked about the Epstein sentencing at his confirmation hearing. There had been no new evidence discovered about Epstein. The renewed interest in the case has to do with the #MeToo movement and the Miami Herald re-reporting on the case.
From what I’ve been reading over the last few days, Acosta was told by the FBI (the Mueller FBI) that Epstein was going to be a protected informant against Bear Sterns and that’s why he was given that ridiculous sentence.
There have been some recent developments, that may have contributed to renewed interest in Epstein.
A long-running civil suit against him by victims was finally settled several months ago.
Mike Cernovich won a court battle to have thousands of pages of documents released - just days before Epstein’s arrest.
On 30 June, Democrat-appointed Judge Christopher F. Droney on the Second Circuit Court (which has jurisdiction over cases in New York) vacated his seat and goes into senior status. That is the decisive vacancy that can enable President Trump and Mitch McConnell to flip that Court to majority Republican-appointees.
