As first reported in this newsletter on Friday, U.S. Sen. Tammy Duckworth traveled to Iraq for the first time since the one-time Army pilot’s Black Hawk helicopter was shot down during Operation Iraqi Freedom in 2004, forever altering the course of her life. And in her first interview about the experience, the Hoffman Estates Democrat talked to me about how the emotions “snuck up” on her, that the very familiar sights, smells and sounds of the places she visited made her long to be a soldier again and wonder where the long war-torn Iraq is headed.
