(CNN)- Sharron Angle's latest campaign ad has been knocked to the mat.
The ad was removed from YouTube hours after its release because of a copyright claim made by Zuffa LLC, the Las Vegas-based parent company of the Ultimate Fighting Championship.
It is unclear what part of the ad is in question. The Angle campaign referred questions about the copyright claim to Zuffa. A Zuffa spokesman has not returned CNN's request for comment.
The ad, entitled "Supermodels," makes an issue of opponent Harry Reid's lifestyle, and contrasts it with the hardships faced by average Nevadans.
"While your family is just hanging on, someone's been hanging out with supermodels," an on-screen narrator says, pointing to a photo of Reid with a blonde supermodel.
The ad goes on to contrast Reid's luxury apartment at the Ritz Carlton in Washington with the fact that Nevada has the nation's highest foreclosure rate. Angle has frequently targeted Reid's apartment; it was the focus of another ad released yesterday, and was brought up by Angle in last Thursday's debate.
Some bloggers have also criticized the ad, which contains a heavily edited image of Reid.
"While you may be in the unemployment line, someone's more likely to be in a conga line," the narrator says while pointing to a photo of the Senate majority leader holding a woman's outstretched arms.
But, the photo has been reversed and cropped so that only the woman's arms are visible. Those arms belong to none other than first lady Michelle Obama, who posed with Reid at an event promoting her physical fitness initiative.
