 Connecticut Senator Greenwich resident Richard Blumenthal was in East Haven this week pushing for technology to help keep kids safe in hot cars. He's calling for all new vehicles to come with sensors to alert drivers if a child's been left behind. He was joined by the town's mayor, first responders, and a dog named Riggs, who was rescued from a hot car last year. Blumenthal says he's asking the state DOT to issue a rule that mandates all cars to have the new system.
