Sentencing for liquor-heiress turned Nxivm financier Clare Bronfman and the bookkeeper for the alleged upstate sex cult has been set for dates in January in Brooklyn federal court, officials said Friday.

Bronfman, co-defendant Kathy Russell and three other defendants copped to guilty pleas in the case — leaving alleged Nxivm leader Keith Raniere to go to trial alone.

Bronfman, who is set to be sentenced before Brooklyn federal judge Nicholas Garaufis on Jan. 8, 2020, pleaded guilty to charges of concealing and harboring an illegal alien for financial gain, as well as fraudulent use of identification and faces up to 25 years in prison.

But federal sentencing guidelines call for the Seagram’s heiress, who owns her own island but never finished high school, to receive a prison sentence ranging between 21 and 26 months.

Russell, who will be sentenced on Jan. 29, 2020, pleaded guilty to visa fraud and faces up to ten years in prison, though sentencing guidelines call for her to receive between six months and a year in the slammer.

Raniere, the so-called “Vanguard” who allegedly ran a secret sex-slave group within Nxivm called “DOS,” was convicted of rackeeting, sex trafficking, related conspiracy charges and other charges following a grueling, six-week trial.

Garaufis said at a recent hearing that before Raniere, who was convicted of racketeering and several other charges and faces up to life in prison, will be likely be sentenced sometime early in 2010. But no firm date has been set.
