A group of Republican senators is demanding the Trump administration label goods made in the West Bank as “Made in Israel.”

On Monday, Sens. Tom Cotton of Arkansas, Marco Rubio of Florida, Ted Cruz of Texas and Kelly Loeffler of Georgia wrote a letter to US President Donald Trump. In it, they said US customs policy should stipulate that products made in the Palestinian territory of the West Bank should be labeled as “Made in Israel.” As of now, such products are labeled “Made in West Bank”; this policy dates back to the administration of President Bill Clinton.

The senators said Trump should continue to support Israel with the policy change. They also want to strike a blow to the boycott, divestment and sanctions (BDS) movement, which supports various economic boycotts against Israel over its treatment of Palestinians.

“Your administration should continue its string of pro-Israel policy changes by undoing these misguided Clinton-era guidelines,” wrote the senators. “This decision would be yet another achievement by your administration that would support Israel and would push back against anti-Semitism and the BDS movement.”
