Inside Waltz’s ouster: Before Signalgate, talks with Israel angered Trump

President Donald Trump’s decision to oust his national security adviser, Michael Waltz, was the product of a slow accumulation of frustration with a former Green Beret officer who was seen as far more eager to use military force than his boss in the Oval Office.

Waltz’s fate was sealed by his inclusion of a journalist on a sensitive Signal group chat in March. But he had been clashing with other top officials since early in the administration, including over whether to pursue military action against Iran, senior officials and Trump advisers said Friday.
