NEWARK - Newark Mayor Cory Booker has finished his food stamp challenge.
Booker stopped living on the equivalent of food stamps at midnight Monday.
He says it was difficult to live on about $4 a day worth of food and give up caffeine for a week.
Booker says he accomplished his goal of starting a national conversation about food stamps.
The idea started when Booker challenged a Twitter user that the two spend the week living on food stamps.
