NEW YORK (AP) — A judge has begun instructing the jury at R. Kelly’s sex trafficking trial on the law after it heard a prosecutor give a fiery rebuttal to defense closing arguments that portrayed him as a victim of lying accusers.

The jury is expected to begin deliberating later Friday. Prosecutors said in closing arguments that there’s ample evidence the R&B star sexually exploited women, girls and boys for more than two decades.

The 54-year-old Kelly has pleaded not guilty to racketeering charges. He is also charged with violating a law that makes it illegal to transport anyone across state lines “for any immoral purpose.”
