Trump Security Adviser Resigns After Signal Chat Leak

U.S. National Security Advisor Mike Waltz is set to step down after accidentally adding The Atlantic’s editor to a Signal group chat that discussed sensitive U.S. military plans for airstrikes on Houthi rebels in Yemen, leading to the exposure of attack details to a journalist hours before the strikes. Waltz, a former Florida congressman, has taken responsibility for the breach, while the White House asserts that no classified information was compromised. His deputy, Alex Wong, is also expected to leave the administration, marking the first major staff shakeup of President Trump’s second term, which had previously been more stable. The departures come amid pressure from far-right influencers and some Trump allies who questioned Waltz's loyalty and operational security. Although Trump initially defended Waltz, frustration reportedly grew within the administration. Potential replacements include special envoy Steve Witkoff, though concerns have been raised about his lack of national security experience.
