Perez's trial on bribery and attempted extortion charges is scheduled to begin Wednesday in Hartford Superior Court. He has denied any wrongdoing and vows to clear his name.
The Democratic mayor was arrested in January 2009 on charges he received a bribe in the form of home improvements from a city contractor, who also was charged.
He was arrested again in September, when state authorities charged him and former Hartford state Rep. Abraham Giles with trying to extort $250,000 from a developer who wanted to buy city-owned property. Giles also denies wrongdoing.
The trial will be heard by a six-person jury and is scheduled to last through the end of June.
