The Israeli government was not shown the memorandum of understanding drafted to end the war with Iran, an Israeli government official told NBC News on Wednesday, the latest sign of growing tension between the United States and Israel.

Shortly after Donald Trump said he had given a copy of the MOU to Israel, the same source said Israel still hadn’t seen the draft. The source wouldn’t comment on whether or not Israeli diplomats had asked for the text and were denied it.

The Israeli government’s absence in the negotiations leading up to the MOU has become a perilous hindrance for Prime Minister Benjamin Netanyahu, who faces career-defining elections before the end of October. The deal framework was provided to NBC News by a senior U.S. official later on Wednesday.
