From The New York Times:
Recent U.S. intelligence reports have raised concerns about Israeli spy agencies eavesdropping on American negotiators working on a peace deal with Iran, amid rising concern over a more general counterintelligence threat by Israel. Israel and the United States have long known, and tolerated, that each was spying on the other. But an intensified Israeli effort to learn about U.S. positions in talks with Iran has crossed a line, according to some American officials.
The reports include concerns that Israel has stepped up its efforts to eavesdrop on senior American officials, including Steve Witkoff, President Trump’s top negotiator, Elbridge A. Colby, the Pentagon’s top policy official, and one of his main deputies, Michael P. DiMino IV.
