TAMPA — Actor Danny Glover and one of reggae legend Bob Marley’s sons are voicing their support for Grammy-winner Buju Banton, who is awaiting sentencing in a drug trafficking case.

The Jamaican singer was convicted in February in Tampa federal court of conspiring to set up a cocaine deal in 2009. He faces a mandatory minimum 15-year prison sentence.

In court documents filed Thursday seeking a shorter sentence, Banton’s attorney, David Markus, included letters of support from the singer’s fans and some of his 15 children.

Glover wrote that Banton is a role model and spiritual leader. Reggae singer Stephen Marley wrote that Banton “has inspired and uplifted many” throughout his career.

Atlanta Hawks basketball player Etan Thomas wrote that he still hopes to include Banton in a book he’s planning about fatherhood.

Banton’s sentencing is June 23.
