The Pentagon's internal watchdog has determined that Defense Secretary Pete Hegseth endangered American personnel and missions by sharing sensitive details about a military strike against Yemen's Houthi rebels using the Signal messaging app. The investigation found that Hegseth violated Pentagon policy by using his personal device for official business and recommended improved training for officials, though it did not conclude he improperly declassified information. Hegseth declined to be interviewed but maintained that he only shared unclassified information and had the authority to declassify as needed. The incident has prompted bipartisan concern among lawmakers and military families, with many arguing that such actions would have led to disciplinary measures for lower-ranking personnel. The findings come amid broader scrutiny of Hegseth's conduct, including a separate investigation into a controversial military strike in the Caribbean Sea.
