Polk County Sheriff's Deputy Dan Charleston is reportedly being investigated for posts on his Facebook page about Muslims.
In a brief message to WHO Radio News Charleston writes that he is "...restricted from commenting about an internal investigation." But, adds: "Truth always rises to the top in time."
The Iowa Informer reports one includes a picture with the heading: verses from the Koran that inspire terrorists. The post says: "No reasoning with this evil ideology."
Dan Charleston has run for the Polk County Sheriff's job twice in past elections, and has been a critic of Sheriff Bill McCarthy.
