A coalition of influential Jewish American groups seeking peace between the Israelis and the Palestinians wants President Joe Biden to revoke a planned Trump administration policy that treats occupied territory crucial to a future Palestinian state as already part of Israel .

In a letter sent to Homeland Security Secretary Alejandro Mayorkas on Tuesday and shared exclusively with HuffPost, the six groups warned the Biden administration against the looming change, which they say would worsen tensions in the Middle East if allowed to go into effect.

Weeks before Trump left office, he directed the Department of Homeland Security to adopt new labels for products made in the section of the West Bank that is under full Israeli control. That segment, known as Area C, forms the majority of the disputed region and hosts Israeli settlements widely viewed as violating international law. The agency is currently set to enforce a March 23 deadline for companies to tag products from the area with language along the lines of Made in Israel including goods made by Palestinians.

It is a powerful symbolic move. The Palestinian Authority, the most powerful governing body among the Palestinians, called Trumps action a war crime at the time of the announcement.
