PHOENIX (AP) - The Maricopa County Sheriff's Office is reviewing Sheriff Joe Arpaio's security following a shooting scare involving CNN commentator Lou Dobbs.

A bullet struck Dobbs' New Jersey home on Oct. 5. On his radio show this week, Dobbs connected the gunshot to his advocacy for a crackdown on illegal immigration.

Sheriff's spokesman Ryan Lee says the department is concerned for Arpaio's safety considering that both he and Dobbs are extremely vocal about their stance on illegal immigration.

Lee also points to protests Arpaio's television and newspaper interviews have incited.

Arpaio's security detail is looking at the current level of security provided to the sheriff and whether or not more security is now warranted.
