Secret Service spokesman Ed Donovan told The Associated Press that the large black doll was found Saturday morning along Main Street in the small town of Plains.
According to footage from WALB-TV, the doll was hanging by a noose in front of a red, white and blue sign that says "Plains, Georgia. Home of Jimmy Carter, our 39th President." A witness told the television station that the doll wore a sign with Obama's name on it.
Donovan said the doll was removed Saturday. He declined further comment.
Officials in the Sumter County Sheriff's Department referred all calls to the Secret Service.
