NEWTOWN, Conn. (AP) — A grass-roots group involving several people who lost loved ones in the Newtown school shooting has a new campaign to address gun violence. It's now reaching out to parents around the country after seeing its push for federal legislation fall short in Washington.

The group, Sandy Hook Promise, formed shortly after the Dec. 14 massacre of 26 people at the Sandy Hook Elementary School. Its goal is turning the tragedy into a moment of transformation for a horrified nation.

The group announced Thursday that it aims to recruit 500,000 parents to its cause in the month between now and the anniversary of the shootings. The campaign will raise awareness about programs that could be implemented locally to prevent violence.
