Some 60 people were on hand at the Coffee Connection in Knoxville Saturday to hear what potential 2016 presidential candidate Rick Santorum had to say.

Santorum told KNIA/KRLS News a lot more people are asking about national security than they were four years ago when he ran for president. He says many are concerned with incidents around the world, the status of countries like Israel and Iran, as well as recent arrests in the United States of terrorists siding with ISIS.
Santorum said he was encouraged by the number people who said they would support him if he decided on another run at the presidency.
