For six years, between 2001 and 2007, Jeffrey Epstein allegedly ran a sex trafficking ring that preyed on minor girls as young as 13. So why was he given a slap on the wrist by federal prosecutors in Florida? Senators, both Republican and Democrat, are asking the same question. Sen. Ben Sasse, R-Neb., wrote a series of letters to the Department of Justice last week, calling for the DOJ's inspector general to review the handling of the case as well as for a congressional review of the "decision-making" process. While the criminal case has been resolved, many questions remain. According to extensive reporting by the Miami Herald, Epstein recruited, manipulated and lured at least 80 girls to his mansion in Palm Beach, Florida and elsewhere, then sexually abused them. Congress has passed stringent laws for sex trafficking and sexual exploitation of minors because these are heinous crimes. Epstein, however, was able to escape this punishment, despite alleged crimes that by all accounts were indeed heinous. The known facts in this case cry out for an official, thorough inquiry. Why were the identities of minor victims turned over to Epstein's attorneys? The government's agreement to suspend and hold in abeyance any grand jury investigation for other people potentially involved in these crimes is simply baffling.
