Scott Rothstein’s journey ended in a small federal courtroom Wednesday: from workaday employment lawyer to a power broker who rubbed elbows with politicians and celebrities to convicted felon.

From a law firm leader who sported $3,000 suits and signed generous checks to political candidates and charities to disbarment and a possible 100-year prison sentence wearing only prison garb for perpetrating a $1.2 billion Ponzi scheme built on nonexistent legal settlements.
