Michigan Sen. Elissa Slotkin has been notified that the Trump administration is investigating her after she organized and appeared in a video with other Democrats urging military service members to resist “illegal orders.” A source with knowledge of the situation confirmed the matter to The Associated Press. The source was not authorized to discuss the matter publicly. Slotkin first posted the video on her X account in November. The inquiry marks another escalation in President Donald Trump’s reaction to a video that he and his aides have labeled as “seditious." Defense Secretary Pete Hegseth has censured Arizona Sen. Mark Kelly, a former Navy pilot and astronaut, for participating.
