Taitz responded a post on her website, attacking McCain, who is being challenged by Hayworth in the GOP primary, for “ignoring the most important issue the country is facing today.”

Taitz called the ad – which she misspelled as “add” throughout the post – “despicable” and “appalling.”

She went on to challenge the four-term senator to a televised debate on the president’s citizenship.

“Senator McCain owes me and my clients an apology and an opportunity to discuss this matter with him on the merits on the national TV, as his add was shown all over the national TV and all over the internet, on a widely watched show, such as Sean Hannity[’s] show,” she wrote.
