Meanwhile, reporter Scott McFarland quoted Ansari as saying, “Only Congress has the power to declare war, not a rogue president or his lackeys. Hegseth’s reckless endangerment of U.S. service members and repeated war crimes, including bombing a girls’ school in Minab, Iran, and deliberately targeting civilian infrastructure are grounds for impeachment and removal from office.”
Ansari is not the first to suggest impeaching Heges for war crimes. Last December, Rep. Shri Thanedar, a Michigan Democrat, submitted articles of impeachment against the Secretary of Defense. However, he stopped short of forcing a vote on the matter. Sen. Chris Murphy, D-Conn., and other lawmakers said the attack on the country’s civilian infrastructure constituted a clear war crime.
