Former Trump Adviser Mike Waltz Faces UN Ambassador Hearing Over Signal Chat Controversy

Mike Waltz, former national security adviser and President Donald Trump’s nominee for U.S. ambassador to the United Nations, is set to face a Senate Foreign Relations Committee confirmation hearing following his ouster over the 'Signalgate' controversy, where he mistakenly added a journalist to a Signal chat discussing sensitive military plans against Houthi militants in Yemen. Waltz has publicly taken responsibility for the incident, while Defense Secretary Pete Hegseth, who shared the war plans in the chat, retains Trump’s support. Despite anticipated tough questioning from Democrats about the mishandling of information and broader Trump administration foreign policy—especially regarding the Middle East, Russia, and the U.N.—Republicans’ 53–47 Senate majority is expected to ensure Waltz’s confirmation. Trump's decision to nominate Waltz aims to fill a long-vacant Cabinet position after previous nominees withdrew, and comes as the U.N. faces significant changes due to U.S. funding cuts and shifting foreign policy priorities. The hearing will also scrutinize Waltz’s views on ongoing global conflicts and the U.S. relationship with international institutions. While the controversy is likely to dominate the proceedings, sources suggest it is unlikely to derail Waltz’s appointment.
