Trump Ousts Waltz After Signal Messaging Scandal

President Donald Trump removed Mike Waltz as national security adviser after the 'Signalgate' scandal, in which Waltz and other officials used the Signal app for sensitive military discussions and inadvertently included The Atlantic's editor in a confidential group chat. Waltz was photographed using what appeared to be a modified version of Signal during a Cabinet meeting one day before his ouster, intensifying criticism. Trump announced Waltz will be nominated as U.S. ambassador to the United Nations, subject to Senate confirmation, with Secretary of State Marco Rubio serving as interim national security adviser. The White House defended Signal's use on government devices, but concerns remain about security and records retention. Defense Secretary Pete Hegseth is also under investigation for his role in sharing sensitive information via Signal. The incident has heightened scrutiny of digital security and exposed internal divisions over foreign policy and communication protocols.
