Sandy Hook Promise, formerly known as Newtown United, plans to announce the effort Monday at 11:00 a.m.
The group says it invited victims' families to the event. Co-founder Tim Makris has said that the group does not represent or speak for the families.
Makris says he's not sure how many families might participate.
A gunman shot his way into Sandy Hook Elementary School on Dec. 14 and killed 20 first-graders and six women before committing suicide as police arrived. He also killed his mother before driving to the school and carrying out the massacre.
