Michigan senator Elissa Slotkin said on Tuesday that she was under federal investigation for her participation in a video last year in which she and fellow Democrats implored troops to refuse illegal orders.

Slotkin, a former CIA officer and veteran who served three tours in Iraq, organized the video with five other Democrats with military and intelligence backgrounds. Donald Trump called it “seditious behavior by traitors” that was “punishable by death”, an assertion that caused outrage and was quickly walked back by the White House, which clarified that the president did not want to execute members of Congress but wanted to see them “held accountable”.

It is unclear what possible crime investigators are probing. The video’s core message – that military officers have a duty to resist unlawful commands – is a fundamental principle of US military law, international law and the US constitution.
