BRIDGEPORT, Conn. (AP) - A Connecticut judge will hear arguments on whether gun maker Remington Arms' company documents should be sealed from public view as it fights a lawsuit filed by families of some of the victims of the 2012 Sandy Hook Elementary School massacre.

A court hearing is set for Thursday in Bridgeport.

Madison, North Carolina-based Remington Arms is the parent company of Bushmaster Firearms, which made the AR-15-style rifle used to kill 20 first-graders and six educators at the school. The families of nine victims killed and a teacher who survived allege the company should not have sold such a dangerous weapon to civilians.

Remington wants many company records requested by the families' lawyers sealed from public view, saying disclosing them would hurt the company financially and benefit competitors.
