The victims in the ad object to County Executive Robert Astorino's decision to bring gun shows back to the Westchester County Center, where they had previously been banned prior to his election.
The family members featured in the ad will join Bramson, a Democrat, at a news conference outside of the County Center to call for a permanent ban on gun shows at the venue.
The Westchester County Center is at 198 Central Ave. in White Plains.
