Trump ordered a 90-day review of America’s presence in UNESCO back in February, with special emphasis on probing “anti-Semitism or anti-Israel sentiment.”

One of the United Nations' UNESCO program missions is the World Heritage program, which protects historic and cultural sites.

The decision comes roughly two years after former President Joe Biden reentered the U.N. Educational, Scientific and Cultural Organization, following Mr. Trump's decision to withdraw the U.S. from the entity during his first term.
