Rep. Jason Crow, D-Colo., talks during an interview with The Associated Press in his office on Capitol Hill in Washington, Dec. 15, 2021. Two decades ago, Crow was a 24-year-old platoon leader in the American invasion of Iraq. Platoon members carried gas masks and gear to wear over their uniforms to protect them from the chemical weapons the U.S. believed – wrongly – that Iraqi forces might use against them. Today, Crow sits on committees that oversee the U.S. military and intelligence agencies. (AP Photo/Susan Walsh, File)
