A lobbyist who admits he accepted bribes in an FBI sting that landed Miami Lakes mayor behind bars is expected to testify against Michael Pizzi this week.

Richard Candia will be federal prosecutors' star witness.

Pizzi denies he did anything illegal.  He's charged with taking nearly $7,000 in bribes for supporting grants pitched by undercover FBI agents.

Candia is expected to get two years in federal prison for pleading guilty to fraud conspiracy.
