Hillary Clinton criticized Republican presidential candidate Mike Huckabee for invoking the Holocaust while criticizing the Iran deal, and she called on the rest of the 2016 field to do the same.

"Comments like these are offensive and they have no place in our political dialogue. I'm disappointed and I'm really offended personally," Clinton said after a speech on the environment in Iowa. "I know Governor Huckabee and I have a cordial relationship with him, he served as governor of Arkansas. But I find this kind of inflammatory language totally unacceptable."

Today, President Obama criticized Huckabee for saying the signing of the Iran deal "will take Israelis and march them to the door of the oven." Obama responded that Huckabee's comments would be "ridiculous if it weren't so sad."

Hillary Clinton, who supported Obama's Iran deal, has also expressed her support for Israel even in the case of a nuclear Iran. She called on other 2016 candidates to similarly condemn Huckabee's comments, as she believes such extreme comparisons have no place in the current debate.

"One can disagree with the particulars of the disagreement to put a lid on the nuclear problem of Iran and that's fair game," Clinton added, "but this steps over the line and it should be repudiated by every person."
