Dr. Laura Schlessinger's racial comments this week, which included several uses of the “N Word” on her radio show, have prompted at least one advertiser to review its status as a sponsor of the show.

Shelly Whitaker, a spokesperson for Advance Auto Parts, said the company is investigating the comments and will review them before deciding to continue with its advertising through a national media buy.

“Now that we are aware of those comments, we will certainly investigate the comments and review our radio buys and make a decision,” she told me. “It is something that we want to investigate further. We will make a well-thought-out decision.”

Whitaker's reaction follows revelations Thursday that Schlessinger had used the “N Word” during a harsh tirade against an African-American woman who had called in seeking advice on her interracial marriage.

Schlessinger accused the woman of being too hypersensitive, but did not use the “N-Word” to describe the caller. She did issue an apology for the comments.

Whitaker had no other reaction to the specific racial statements Schlessinger made.

Other advertisers reached by Media Matters who declined initial comment include Pfizer, Blinds.com, Solar Universe and California Southern University.

Cliff Scott, director of media and public relations for California Southern University, said his college had just launched a national ad campaign in more than 300 markets, which included the Dr. Laura spots.

But he declined comment, stating he had not heard the controversial remarks.

“She is one of the people whose shows we are syndicating with,” he said.
