A talk-radio host in his book has accused Madonna - who has adopted the Jewish mysticism Kabbalah - of being responsible for the spiritual weakening of the US.

In his "Liberalism Is a Mental Disorder", Michael Savage was quoted by the New York Post as holding the pop diva responsible for spreading a "godless worldview".

"Here's a woman who made a career as a pseudo-pornographic belly dancer cavorting with a whip, and now suddenly, after having a baby, she pretends to be a holy woman riding her bicycle in England on her country estate with her buddy, Gwyneth Paltrow," the ultra conservative talk-radio host said.

"They both fled America because America wasn't clean enough for their offspring. In Madonna's view, we're a spiritually bankrupt nation - which she helped create. What could Madonna know about the sacred arm of Judaism? Answer: Nothing!"
