CHICAGO (AP) — A judge has set an April 27 trial date in R. Kelly’s federal case in Chicago that accuses the R&B star of child pornography and obstruction of justice.

But the judge said at a Wednesday status hearing the date could be moved since the 52-year-old faces similar cases in three other judicial districts.

Kelly stood in court in orange jail clothes, his hands behind his back. Several supporters waved at Kelly as he was led back to jail and he nodded in their direction.

Kelly attorney Steve Greenberg told the hearing that having to prepare for four trials is challenging and he wasn’t sure the singer’s legal team could ready by April. Prosecutor Angel Krull estimated a trial would last three weeks.
