The Senate has confirmed Mike Waltz as the U.S. ambassador to the United Nations, following months of delays and setbacks. This confirmation comes just days before a major global summit and follows a narrow vote. Waltz, a former national security adviser under Trump, faced challenges during the confirmation process, leading to concerns about his ability to represent the U.S. at upcoming international meetings. The World Jewish Congress has welcomed his appointment as Washington prepares for the annual gathering of world leaders.
