The esteemed PBS journalist today recalls another race-based incident involving the radio host who’s in hot water for using the phrase “nappy headed ho’s”:

I was covering the White House for this newspaper in 1993, when Mr. Imus’s producer began calling to invite me on his radio program. I didn’t return his calls. I had my hands plenty full covering Bill Clinton.

Soon enough, the phone calls stopped. Then quizzical colleagues began asking me why Don Imus seemed to have a problem with me. I had no idea what they were talking about because I never listened to the program.

It was not until five years later, when Mr. Imus and I were both working under the NBC News umbrella — his show was being simulcast on MSNBC; I was a Capitol Hill correspondent for the network — that I discovered why people were asking those questions. It took Lars-Erik Nelson, a columnist for The New York Daily News, to finally explain what no one else had wanted to repeat.

“Isn’t The Times wonderful,” Mr. Nelson quoted Mr. Imus as saying on the radio. “It lets the cleaning lady cover the White House.”

I was taken aback but not outraged. I’d certainly been called worse and indeed jumped at the chance to use the old insult to explain to my NBC bosses why I did not want to appear on the Imus show.

I haven’t talked about this much. I’m a big girl. I have a platform. I have a voice. I’ve been working in journalism long enough that there is little danger that a radio D.J.’s juvenile slap will define or scar me. Yesterday, he began telling people he never actually called me a cleaning lady. Whatever. This is not about me…
