Gun control advocates Lynne Prather (L) of Oakland, CA, and Julie Huff of Silver Spring, MD, roll up a banner after after police asked them and others to clear Pennsylvania Avenue in front of the White House August 15, 2016 in Washington, DC. Prather and Huff joined other demonstrators from We the People for Sensible Gun Laws to protest in front of the White House as they have every Monday for the last four years. Uniformed Secret Service officials temporarily cleared pedestrians from the north side of the White House without giving cause. (Photo by Chip Somodevilla/Getty Images)
