According to this article, Acosta helped Epstein get the sweetheart deal in the first place. Doesn't look like he's into taking anyone down I hate to say.

................. The deal, called a federal non-prosecution agreement, was sealed so that no one — not even his victims — could know the full scope of Epstein’s crimes and who else was involved. The U.S. attorney in Miami, Alexander Acosta, was personally involved in the negotiations , records, letters and emails show.

Acosta is now a member of President Donald Trump’s Cabinet. As U.S. secretary of labor, he has oversight over international child labor laws and human trafficking and has recently been mentioned as a possible successor to former U.S. Attorney General Jeff Sessions, who resigned under pressure in early November.
