The Trump administration on Thursday said it would withdraw the United States from the United Nations Educational, Scientific and Cultural Organization (UNESCO), citing anti-Israeli bias from the organization.

UNESCO was informed of the administration's decision on Thursday. The State Department said the U.S. would instead seek to be a permanent observer to UNESCO, which promotes collaboration among countries through culture, education and science.

“This decision was not taken lightly, and reflects U.S. concerns with mounting arrears at UNESCO, the need for fundamental reform in the organization, and continuing anti-Israel bias at UNESCO,” State Department spokeswoman Heather Nauert said in a statement.

This is not the first time the United States has withdrawn from the organization, nor is it the first time the United States has criticized UNESCO for anti-Israeli bias. The United States also withdrew from the organization during the Cold War under President Ronald Reagan.

During the Obama administration, the U.S. slashed $80 million per year of its funding for the organization, according to Foreign Policy, a move that followed UNESCO’s admittance of Palestine as a member.

The cuts have increased the money owed by the United States to UNESCO to $500 million, the magazine reported.

Fights over Israel and the Palestinian cause have been frequent flashpoints for the United States under past administrations.

Israel last year summoned its UNESCO ambassador after the organization declared that one of Jerusalem’s holy sites is specifically a “Muslim holy site of worship,” according to Reuters.

The U.S. will still be involved with the organization “as a non-member observer state,” the State Department said.

The goal is “to contribute U.S. views, perspectives and expertise on some of the important issues undertaken by the organization, including the protection of world heritage, advocating for press freedoms, and promoting scientific collaboration and education.”

The withdrawal will become official on Dec. 31, 2018.
