Herman Cain on Sunday slammed fellow Republican presidential candidate Rick Perry over a sign on his ranch that used a racial slur.
The Washington Post reported Saturday that in the early years of political career, Perry had hosted hunting parties at his family's ranch, a place known as "Niggerhead."
A sign bearing that name had been at the entrance of the ranch when Perry's father painted over it in the 1980s.
"That is very insensitive," Cain told ABC's Christian Amanpour Sunday. "There are some words that do not basically inspire the kind of negativity like that particular word. I know that you are refraining from saying that word so I'm going to say what the word was on the rock -- the name of the place was called 'N*ggerhead.'"
"That is very insensitive and since Gov. Perry has been going there for years to hunt, I think it shows a lack of sensitivity for a long time not taking that word off of that rock and renaming the place. It's just basically a case of insensitivity."
In a statement, the Perry campaign pushed back on details in the Post's story.
"A number of claims made in the story are incorrect, inconsistent, and anonymous, including the implication that Rick Perry brought groups to the lease when the word on the rock was still visible," Perry campaign communications director Ray Sullivan said. "Perry's father painted over offensive language on a rock soon after leasing the 1,000-acre parcel in the early 1980s."
