Two liberal Democrats launched into a verbal argument that turned physical on the floor of the House Thursday night during a debate over an appropriations earmark one was seeking, according to Roll Call. Rep. Maxine Waters, D-Calif., and Appropriations Chairman David Obey, D-Wis., split apart from a heated conversation and began yelling at one another. “You’re out of line,” Waters shot while walking down toward the well. “You’re out of line,” Obey shot back before turning and walking away. But then Obey stopped, turned back toward Waters, and shouted: “I’m not going to approve that earmark!”
