After a rally in front of the White House, students march up Pennsylvania Avenue toward Capitol Hill in Washington, Wednesday, March 14, 2018. Students walked out of school to protest gun violence in the biggest demonstration yet of the student activism that has emerged in response to last month's massacre of 17 people at Florida's Marjory Stoneman Douglas High School.
