NEW YORK • A prosecutor in closing arguments at the sex-trafficking trial of R. Kelly urged jurors on Thursday to make the R&B superstar “pay” for his alleged crimes, while a defense lawyer told them they’ve been misled by opportunistic accusers about consensual relationships.

“It is now time to hold the defendant responsible for the pain he inflicted on each of his victims,” Assistant U.S. Attorney Elizabeth Geddes said in concluding her closing in federal court in Brooklyn that spanned two days. “It is now time for the defendant, Robert Kelly, to pay for his crimes. Convict him.”

Defense attorney Deveraux Cannick countered by telling the jury that testimony by several accusers was full of lies, and that “the government let them lie.”

He added: “Where the fairness to Robert? Where’s the integrity of the system?”

The exchange came with trial nearing jury deliberations after testimony from dozens of witnesses since the beginning of the proceedings on Aug. 18. Jurors could get the case as soon as Friday afternoon.
