On May 1, President Trump reshuffled national security, naming Marco Rubio interim National Security Adviser after Mike Waltz's ousting amid a messaging scandal. Recent photographs revealed top officials, including Waltz, using an unofficial, potentially insecure version of the Signal app, raising concerns over the handling of classified information. The app, TM SGNL, allows message archiving, compromising Signal's end-to-end encryption. Critics worry the restructuring could weaken U.S. foreign policy coherence amidst ongoing economic challenges and diplomatic tensions, amidst growing scrutiny on Defense Secretary Pete Hegseth following revelations of informal communication regarding military actions.
