A new ad from the pro-gun control group Mayors Against Illegal Guns features family members of the people killed at Sandy Hook Elementary in Newtown, Conn.

The 60-second and 90-second ads will run in Connecticut in the Hartford media market as that state's legislature considers new gun laws.

The ad features the father of Jesse Lewis, the parents of Grace McDonnell, the sister of Vicky Soto, and the parents of Lauren Rousseau.

"Don't let the memory of Newtown fade without doing something real," Rousseau's mother, Terri Rousseau, says at the end of the ad.

In a particularly moving moment, Rousseau's father, Gilles, notes that Lauren "died doing" what she felt passionate about -- teaching little kids. He then breaks down and says, "Wonderful."

The ads were first reported by Politico.

Mayors Against Illegal Guns was founded by New York Mayor Michael Bloomberg, who is also spending $13 million on ads urging key senators to vote for the looming gun control package.

Connecticut's legislature has been working on gun control for months and has missed self-imposed deadlines for dealing with the issue. Meanwhile, New York and Colorado have been the first states to enact new gun laws in response to the tragedy in Connecticut.
