"We couldn't be more excited to have Taye on the show," the Kings said in a statement. "We've been huge fans for years, and love his ability to play comedy and drama with equal ease."

The highlight of the finale for season 5 was Eli Gould (Alan Cumming) proposing Alicia (Julianna Margulies) become a candidate for State's Attorney. The cliffhanger obviously had to do with the big decision Alicia will have to take now.
