Appearing at a Trenton, N.J., train station with U.S. Sen. Frank Lautenberg and law enforcement officials Monday, Napolitano announced the expansion of the "If You See Something, Say Something" ad campaign across the Garden State, The (Trenton) Times reported Tuesday.
"As we head into this year's busy holiday traveling season, we're talking about the role each individual can play to keep us safe and secure," she said.
The "If You See Something, Say Something" campaign began in New York but the Department of Homeland Security began expanding it nationwide since summer, The Times said.
The broadened New Jersey promotion will include more postings in the state's train and bus stations, materials in movie theaters and gas stations, and advertising on local radio stations, Napolitano said.
"The threat is as real as ever," Lautenberg said. "We have to roll up our sleeves, do what it takes, before a terrorist threat becomes a reality."
