Loughlin and Giannulli will have a chance to address U.S. District Judge Nathaniel Gorton when he decides whether to accept their unusual plea deals with prosecutors, which calls for Loughlin to serve two months in prison and Giannulli to serve five months.
Under the plea deal, Giannulli has also agreed to pay a $250,000 fine and perform 250 hours of community service.
Loughlin and Giannulli will appear before the Boston federal court judge during separate sentencing hearings held via videoconference because of the coronavirus pandemic.
She and Giannulli fiercely fought the allegations for months, with their lawyers accusing prosecutors of withholding evidence that would exonerate them.
They may also be concerned that saying the wrong thing could blow up their deal with prosecutors, lawyers say.
