The company released a statement saying “we believe it is inconsistent with our values for Ben & Jerry’s ice cream to be sold in the Occupied Palestinian Territory.” The company, now owned by global consumer giant Unilever, has sold its brand in Israel for decades through a local Israeli distributor. Unilever said it would seek a new deal to sell ice cream in Israel, but not in territory claimed by Palestinians for a state of their own.In Israel, businesses are prevented from treating customers and subsidiaries differently in what Israel calls “disputed territory” versus those in what much of the world recognizes as Israeli territory. Israeli Prime Minister Naftali Bennett vowed this week to “act aggressively” against the ice cream company, which was founded in 1978 by Ben Cohen and Jerry Greenfield, who are Jewish and progressive-minded.The American flag and the Texas State flag fly over the Texas State Capitol in Austin, Texas.Brian Snyder | ReutersNow, Texas is getting involved. A spokesman for Republican Gov. Greg Abbott told CNBC on Tuesday night: “Ben and Jerry’s decision to boycott parts of Israel is disgraceful and an insult to America’s closest ally in the Middle East.” The statement went on to say: “Unilever, Ben and Jerry’s parent company, must reverse this ill-conceived decision.”Abbott signed a bill into law four years ago that would force Texas pension funds to divest from any company boycotting Israel.State Comptroller Glenn Hegar, who controls billions of dollars in assets for Texas’ public pension funds has already told his office to take action. In a statement to CNBC he said, “I’ve directed my staff to determine whether any specific action has been taken by Ben & Jerry’s or Unilever would trigger a listing under Chapter 808 of the Texas Government Code,” the law passed in 2017.It is also possible sales in states with anti-boycott laws could be impacted. If Ben & Jerry’s or Unilever bids for a contract at a public institution, they could be disqualified if the boycott becomes a reality.Florida state CFO Jimmy Patronis, who controls public pension funds, told CNBC his office started discussing the issue Tuesday morning. “I find what’s taking place very concerning,” he said in a text. But he wasn’t prepared to say what action might be taken.Airbnb was the last company to find itself tangled in a similar issue. In 2018, the rental site said it was banning listings of Israeli property in the West Bank, territory Palestinians claim should be part of their state.

After the conversation, Israel’s new prime minister said: “This is an action that has severe consequences, including legal, and it (Israel) will take strong action against any boycott directed against its citizens.”Ben & Jerry’s Chair Anuradha Mittal has not responded to CNBC regarding the impact of the decision and the possibility that state pension funds could divest from Unilever. In a phone interview Thursday, Ben & Jerry’s spokesman Sean Greenwood said: “The company has nothing to add beyond the original statement” issued Monday.Speaking to NBC News earlier this week, Mittal went after Unilever for issuing its own statement on the issue calling it “deceit.” She added: “I can’t stop thinking that this is what happens when you have a board with all women and people of color who have been pushing to do the right thing.”Unilever has not returned CNBC calls or emails seeking reaction to the possibility of divestment by state pension funds.
