The 'I Believe I Can Fly' singer pleaded not guilty to a racketeering charge during the trial.
He also pleased not guilty to eight counts of violating a federal law making it illegal to transport people across state lines for prostitution.
Jurors have heard testimony from dozens of women throughout the trail which has gone on for over a month.
The R&B singer has been accused of exploiting multiple women and girls over the past quarter-century and still faces sex-related charges in both Illinois and Minnesota.
