Radio host Peter Boyles said he's been asked by Clear Channel officials to not talk about his crude reference to U.S. Rep. Diana DeGette.

He said management at KHOW-AM (630) asked him on Wednesday to stop saying "Vagina DeGette" on the air.

But publicity by media and liberal-leaning Colorado Media Matters continued to keep the incident in the public eye and, in turn, the slur alive.

"I've been asked not to talk about it anymore, and so I won't," Boyles said after his Monday broadcast.

"I'm done with it."

The controversy started after President Barack Obama came to Denver last Tuesday to sign the $787 billion stimulus bill at the Denver Museum of Nature & Science. During introductions, the president mispronounced the name of Diana DeGette, calling the Denver Democrat "Diana DeJette."

Boyles took the opportunity to make fun of the president the following morning by taking the mispronunciation even further - calling her Vagina DeGette.

He said on the air: "It was funny to me. It remains funny to me. I'm not apologetic."

DeGette's office had little comment.

"Vulgar and demeaning personal attacks have no place in our political discourse," said Kristofer Eisenla, DeGette's spokesman. "Therefore, we have no comment."

And from now on, Boyles won't either.

"I don't think he disagreed with (the decision)," said Kris Olinger, Clear Channel's director of AM programming. "It's done. It's over."

But Boyles did spend large chunks of his show Monday talking about the incident.

He told one caller on the air that this was a way for critics who don't like his views on illegal immigration, Mayor John Hickenlooper and Gov. Bill Ritter to get back at him.

"They can't get you for the other stuff, so they get you for this one," he said.
