A Fox News contributor who helped popularize claims that President Barack Obama wasn't born in the United States has done one better, leveling a racist charge against CBS News anchor Katie Couric.

Speaking on Don Imus' Imus in the Morning program, which is simulcast on Fox Business network, Fox News regular and President George H. W. Bush appointee Bo Dietl launched a personal attack on Couric, who some conservatives consider too liberal to be an objective news network anchor.

Dubbing Couric a "cougar" -- a woman who dates younger men -- Dietl continued:

She looks like a Halloween cartoon. She’s got her eyes pulled so far, she’s starting to look Chinese herself. Enough with these face lifts, alright Kate.

And enough with the young guys Katie. You’re over the top baby. You’re over fifty. Start going out with guys your own age. This cougar stuff don’t work.

Later in the interview, he went one further: "You like her eyes the way they look? They’re getting smaller and smaller."

"Ten years ago, she looked American," Dietl remarked. "Today she is an Oriental."

Imus replied by calling Couric a "rodent."

Dietl has appeared on the programs of Fox's Bill O'Reilly, Sean Hannity and Neil Cavuto and numerous times on Imus' Imus in the Morning.

Couric replaced CBS News' Dan Rather in 2006.
