The four-time Grammy nominee faces a possible life sentence if convicted.
Banton's attorney told a jury in Tampa federal court Monday that the singer made "the worst mistake of his life" when he used his finger to taste cocaine in front of an undercover government informant in Sarasota in early December. But David Markus insisted his client didn't participate in any conspiracy to sell drugs.
Prosecutors said Banton was an established drug trafficker by the time he met the informant. They said the singer was looking for "more, new and different money through a new conspiracy he was shopping for" in addition to drug deals he had already financed.
