Sen. Ted Cruz, R-Texas, and Rep. Ileana Ros-Lehtinen, R-Fla., sent a letter this week to the Executive Board of the United Nations Educational, Scientific and Cultural Organization protesting a resolution the U.S. lawmakers say is part of a wider effort to delegitimize Israel.

“The United Nations’ obsessive hostility towards Israel will be on display yet again this week as UNESCO considers another blatantly biased resolution that unjustly singles out our close ally Israel with false accusations and criticism, and attempts to erase the specific deep-rooted, historical connection of Jews and Christians to Jerusalem, Israel’s eternal capital,” Cruz’s office said Tuesday.
