Earlier this month, violent Israeli settlers attacked Palestinian farmers, who were harvesting olives, and a group of journalists. Washington Post photographer Heidi Levine had to be rushed to the hospital with broken bones.

When Israeli troops arrived, rather than restrain the assailants, they fired tear gas at Palestinians, emboldening the settlers further.

This is just one recent example: Nine Americans have been killed in the West Bank in recent years, and even more have been detained. Countless Palestinians, dozens of journalists, and even U.S. politicians have been targeted. No one has received accountability or justice.

A group of lawmakers is trying to change that, and they’re growing in numbers by the day. Fifty-nine members of Congress currently co-sponsor Rep. Joaquin Castro’s Stop the Settlements Act, which would impose U.S. sanctions to stop illegal settlements and outposts in the West Bank and Gaza.
