Former US congresswoman Gabrielle Giffords is set for her first visit to a gun show since she survived an assassination attempt in 2011.
Mr Schneiderman had worked with all 35 gun show operators in New York to adopt stringent new rules to track sales. Mr Schneiderman also has a staff member at each gun show to work with operators to monitor compliance with the state's new gun control law.
Ms Giffords was shot in the head during a meeting with constituents in Tucson on January 8 2011. Six people died in the incident.
