Schmidt is accused of taking a chicken feed bag from the neighbor's home and throwing it in a swamp. She's charged with misdemeanor trespassing and criminal damage to property.
Schmidt's neighbor says the state senator harassed them for more than a year.
Schmidt allegedly accused the female neighbor of having an affair with Schmidt's husband, which the woman denies.
In 2010, Schmidt allegedly had a physical fight with her husband, called police and told them to ignore her husband if he phoned.
