US talk show host Jay Leno has been sued by an Indian-American in California for his "racist" comments on the Golden Temple and ridiculing the entire Sikh community by portraying the holy shrine as a vacation home.

According to court papers filed in Los Angeles Superior Court, Randeep Dhillon claims that Leno "hurt the sentiments of all Sikh people in addition to those of the plaintiff" with his joke that the Golden Temple could be a possible summer home of Mitt Romney, a leading Republican presidential hopeful.
