Joan Rivers hit back at the Anti-Defamation League Friday, after the group criticized her for comparing Costco's decision not to sell her new book to the Nazis.

"My husband lost most of his family in Auschwitz, so don't talk to me about the holocaust," Rivers said in a statement to TheWrap.

The ADL slammed the comedian saying that her remarks were insensitive to the victims of the Holocaust and called on her to retract her comments.

In her statement, Rivers said the group was wasting its energy.

"The ADL should worry more about the world's attitude toward Israel than waste their time and energy on me because I'm not going to stop saying what I think," she said.

The comedian has said in interviews that Costco has refused to carry her new book, "I Hate Everything ... Starting with Me," because the back cover contains swear words.

But what angered the ADL was her comments in an interview Thursday [5] that “People should have the right to have the literature they want. This is the beginning of Nazi Germany.”

In her statement to TheWrap, Rivers reiterated her views that the retailer was on dangerous ground. "Banning books anywhere is a bad portent," the comedian said.

Earlier in the day, ADL National Director Abraham H. Foxman, himself a survivor of the Holocaust, said Rivers should be more careful with her historical analogies.

“Such comparisons only serve to trivialize the Holocaust and are deeply offensive to Jews and other survivors, as well as those Americans who fought valiantly against the Nazis in World War II," Foxman said in a statement.

Rivers' husband, Edgar Rosenberg, died in 1987.
