Jeffrey Goldberg, editor-in-chief of the Atlantic magazine, revealed that he was added to a Signal messaging app group chat containing senior Trump administration officials discussing U.S. airstrike plans against Houthi rebels in Yemen prior to the execution of the strikes on March 15. The group included figures such as national security adviser Michael Waltz, Defense Secretary Pete Hegseth, and Vice President JD Vance. Goldberg expressed skepticism about the legitimacy of using Signal for such discussions, noting that government policy prohibits employees from discussing classified information on messaging apps unless it's forwarded to an official account. The incident has prompted congressional Democrats to call for an investigation, labeling it an "outrageous national security breach."
