PEMBROKE PINES, Fla. — Family members of those killed at a Florida high school joined U.S. Rep. Debbie Wasserman Schultz at a town hall meeting on gun violence.

Wasserman Schultz, a south Florida Democrat, hosted the meeting Saturday at a senior center located about 28 miles (45 kilometers) south of Marjory Stoneman Douglas High School. Seventeen people were shot and killed at the school nearly two months ago.

Fred Guttenberg, whose daughter Jamie was killed, called on the crowd to stand up to “weak-kneed” state legislators who refuse to enact additional gun regulations.

Debbie Hixon, the wife of Chris Hixon, the school’s athletic director who was killed, praised state legislators for passing new gun restrictions this year. But she said that she will continue to push for a ban on the type of rifle that was used at the Parkland shooting.
