Jamaal Bowman, a former middle school principal and advocate for gun control, was confronted by Republican colleague Thomas Massie — days after a 28-year-old former student opened fire inside a private Christian academy in Nashville, Tenn. "They're all cowards! They won't do anything to save the lives of our children. Cowards," Bowman said to reporters assembled outside the House chamber.
