Dozens of Democratic senators are demanding answers from the Trump administration as a growing body of evidence suggests that the U.S. was likely responsible for a strike at an elementary school in Iran that killed over 165 people, many of them children. The letter from more than 45 senators pressed Defense Secretary Pete Hegseth on whether the U.S. was in fact culpable and, if so, what the intended targets were for the strike and what analysis had been done beforehand on the purpose of the building. The senators also raised concerns about the hollowing out of a congressionally mandated office set up specifically to reduce civilian casualties.
