Dozens of progressive, faith, and human rights groups on Monday sent a letter to U.S. Senate leaders and the top lawmakers on the U.S. Senate Foreign Relations Committee, urging them to oppose the nomination of former Arkansas Gov. Mike Huckabee as ambassador to Israel, calling him “unfit” and citing his “extreme views supporting the Israeli government’s genocide of Palestinians.”

The letter was released a day prior to Huckabee’s confirmation hearing before the Senate Foreign Relations Committee. The hearing on Tuesday was interrupted by protestors who had messages such as: “Huckabee uses his Christianity to justify ethnic cleansing.” Huckabee is an evangelical Christian and longtime supporter of Israel who has pushed Christian Zionist views.

Huckabee, who has taken more than 100 trips to Israel since 1973, has “consistently engaged in inflammatory and discriminatory statements that demonize Palestinians and Muslims,” according to the letter.

On the campaign trail in 2008, Huckabee told a rabbi in Massachusetts that “there’s really no such thing as a Palestinian.” During a trip to the West Bank in 2017, Huckabee said: “there is no such thing as a West Bank… There’s no such thing as a settlement. They’re communities, they’re neighborhoods, they’re cities. There’s no such thing as an occupation.”

The letter, which was from over 65 organizations including Jewish Voice for Peace Action, CodePink, and Hindus for Human Rights, argues that Huckabee’s “Christian nationalist beliefs are also inherently a form of antisemitism, as it is predicated on the expulsion of Jews from the diaspora to the land of Palestine and the demonization of Palestinians and Muslims as enemies of God.”

“At a time when the United States should strive to rebuild its credibility, appointing an individual with a history of extremist, apocalyptic, and hateful views to such a critical role would be a grave mistake,” the letter states.

Israel’s deadly campaign on the Gaza Strip that began in October 2023 has now killed over 50,000 people, according to local health officials. Last week, Israel resumed strikes following a cease-fire that last roughly two months after Israel refused to hold talks regarding a permanent end to the war.

At the confirmation hearing, Huckabee attempted to distance himself from his past statements about Palestinians, according to The Associated Press, and said he would “carry out the president’s priorities, not mine.”

The groups who sent the letter Monday are not alone in opposing Huckabee’s nomination. Pro-Israel voices have also said he is not right for the role.

Rep. Jerry Nadler (D-N.Y.), who is Jewish, said in a statement Monday that Huckabee is “woefully unfit” to serve as ambassador to Israel and a “vote for Huckabee is a vote to empower a Christian nationalist vision for American foreign policy.”

Jeremy Ben-Ami, president of the pro-Israel group J Street, said in a statement Monday that Huckabee’s views “would undermine American interests and the administration’s own stated commitment to pursuit of long-term regional peace and security.”

“Mr. Huckabee’s embrace of annexation, extremist settlers, and fanatical Christian Zionism stands in stark contrast to the Jewish, democratic values held by the overwhelming majority of our community—and in stark contrast to Israel’s founding values of justice, equality and peace,” he also said.
