The former Arkansas governor on Saturday praised the decision of the high-ranking Democrat -- a political polar opposite to his evangelical conservative beliefs -- to not support the Iran deal.
"Thank God for Sen. Schumer and his opposition to this reckless nuclear deal with Iran," he said in a statement. "While I disagree with Sen. Schumer on most things, I applaud him for putting peace in the Middle East above partisan politics. Despite endless arm-twisting and enormous political pressure from the White House, Sen. Schumer chose statesmanship over partisanship."
Schumer, an influential Jewish Democrat of New York who's poised to assume leadership of his party in the Senate, announced his decision to oppose the deal on Thursday
"After deep study, careful thought and considerable soul-searching, I have decided I must oppose the agreement and will vote yes on a motion of disapproval," Schumer wrote in a 1,600-word post on the website Medium.
Other influential Jewish Democrats -- including Reps. Steve Israel and Nita M. Lowey -- also oppose the deal. Huckabee said he hopes Schumer's decision encourages other Democrats to do the same thing.
"Sen. Schumer's opposition to the agreement sends a signal to every pro-Israel Democrat in Washington that they don't have to 'walk the plank' for President Obama -- they can stand for peace and reject this bad deal. And I pray that they will," Huckabee wrote.
Fellow Republican presidential candidate Sen. Ted Cruz also praised Schumer's decision during a Q&A with journalists Saturday at the RedState Gathering, a convention of conservative activists.
"Now I know that I'm known as such a vocal advocate of electing democrats, but Chuck Schumer this week came out against this Iranian nuclear deal. That was an act of courage and bravery, and I salute Chuck Schumer for doing it," he said.
The Texas senator said he hoped Schumer's example will inspire other Democrats to take a tough stance on national security.
"There used to be a long tradition of Democrats who were willing to stand up and defend our national security. Sadly, that has become almost an endangered species in Congress," he said. "I hope that Chuck Schumer carries through and doesn't just oppose this deal, but that he helps lead the fight to rally his fellow Democrats to stand together."
