Mayors Against Illegal Guns, a group led by New York City Mayor Michael Bloomberg, released a television ad on Thursday featuring family members of four victims of the Sandy Hook Elementary School shooting last December.
The ad features the families of two first-graders and two teachers killed at Sandy Hook, out of the total 20 children and six adult staffers killed that day. The family members in the ad are Neil Heslin, father of first-grader Jesse Lewis; Chris and Lynn McDonnell, parents of first-grader Grace McDonnell; Jillian Soto, sister of teacher Vicky Soto; and Terri and Gilles Rousseau, parents of teacher Lauren Rousseau.
"I want to prevent any other family from having to go through what we're going through," Chris McDonnell says in the ad.
"Don't let the memory of Newtown fade without doing something real," Terri Rousseau says next.
The ad displays the words "Connecticut can save lives" and calls for comprehensive background checks, a limit on high-capacity magazines and an assault weapons ban.
It is the first to include Newtown victims' family members in a call for universal background checks for gun sales, which will be a component of the gun control legislation being introduced in the Senate. The ads will air on cable and broadcast television in the Hartford, Conn., area and specifically target the state's legislature to enact better gun violence prevention.
More than 120 actions are planned around the United States on Thursday for a day of advocacy on gun violence, including one at the White House. Heslin, Rousseau and the McDonnells will attend the White House event.
