Democratic Massachusetts Sen. Elizabeth Warren threatened to cut off aid to Israel on Sunday while campaigning in Iowa.

The 2020 Democratic presidential candidate accused Prime Minister Benjamin Netanyahu of running afoul of U.S. policy in the region, claiming that Netanyahu was making it harder for Israel and Palestine to reach a two-state solution.

“Would you make American aid conditional on settlement building?” a man asked.

“Right now, Netanyahu says he is going to take Israel in a direction of increasing settlements,” Warren said. “That does not move us in the direction of a two-state solution.”

Netanyahu’s administration has continued building houses in the West Bank in recent years, and Netanyahu has promised to annex existing Israeli settlements in the West Bank.

“It is the official policy of the United States of America to support a two-state solution, and if Israel is moving in the opposite direction, then everything is on the table,” Warren said.

“Everything is on the table,” she continued.
