In January, Biden, D-Del., said that one of Obama's political attributes is that he is "clean." Host Bob Cole of KVET’s “Sam and Bob in the Morning” show reminded listeners Thursday that Biden had used the racially-insensitive word to describe Obama.

"He's clean is what what's-his-name said. Joe Biden told us that," Cole said.

"Clean darky," quipped host Sam Allred.

Cole immediately exclaimed, "Sammy!" The show then cut to commercial. After the break Allred said: "See, I was making fun of politicians who say things like that."

The local NAACP chapter didn’t see it that way. They plan to file a complaint over the remark, and are calling for Allred to apologize publicly.
