When rhythm and blues singer R. Kelly, the three-time Grammy winner, goes on trial in Chicago next month on charges that he produced pornography with an underage teenager, Cook County Judge Vincent Gaughan wants to be ready for the barrage of publicity that will follow the pop star.

Gaughan, who will be presiding over the trial, traveled with other county officials last year to California to meet with Santa Barbara County Superior Court officials and study how the court’s Santa Maria unit handled the 2005 Michael Jackson criminal trial.
