Fox News host Mike Huckabee warned last week that abortion rights could lead to a Nazi-style extermination of elderly people in the United States.

"The fact is we live in a country that has always valued the notion that every person has worth and value," the former Arkansas governor said at Susan B. Anthony List's 7th Annual Campaign for Life Gala. "And I want us to be reminded of what takes place when a country begins to devalue any group of its citizens for any cause whatsoever. Once the devaluation of a certain segment of the population occurs, whether it is because of gender, religion, race, creed, color -- or the age of gestation -- then anything is possible."

Huckabee said he visited the notorious Nazi concentration camp Auschwitz earlier this year.

"We look at the horrors of the Holocaust and people say, 'How could that happen? How could one of the most sophisticated, well educated and scientifically advanced countries in the entire planet do something of such magnitude?' And I tell you, it didn't happen over night. It happened slowly but methodically, human beings were devalued."

Huckabee said women only terminated their pregnancies because "some lives are a financial hardship" or because being pregnant is "a social disruption." He warned that abortion rights could lead to the killing of elderly citizens in the name of convenience.

Huckabee has a long history of comparing abortion to the Holocaust. The Anti-Defamation League called on Huckabee to stop making the comparison in 2007.

"We find the use of analogies to the Holocaust in other contexts deeply painful, disturbing and offensive. Such analogies can only trivialize and diminish the horror, and cause further pain to Holocaust survivors and to those alive today who lost friends and loved ones," ADL National Director Abraham H. Foxman said.
