(CNN) - Israeli sources tell CNN’s Wolf Blitzer that the White House rejected Israeli Prime Minister Benjamin Netanyahu’s request to meet with President Obama later this month to discuss Iran’s nuclear program.

On CNN’s “The Situation Room,” Blitzer reports that the Israelis were told a meeting isn’t possible because the President’s schedule won’t permit it, even when the Israelis offered to have the Prime Minister come to Washington from New York, where he will be addressing the United Nations.

The White House is pushing back, saying the President and Prime Minister simply won’t be in New York at the same time, but this is the tip of the iceberg in a much bigger disagreement over Iran’s suspected quest for nuclear weapons.
