Sen. Chris Murphy (D-CT) (L) and Sen. Richard Blumenthal (D-CT) address the National Rally to End Gun Violence on the West Lawn of the U.S. Capitol September 25, 2019 in Washington, DC. George Scott was shot and killed in San Francisco in 1999. Organized by Rev. Michael Pfleger of St. Sabina Catholic Church in Chicago, the Newtown Action Alliance and other gun violence prevention organizations, participants called on U.S. President Donald Trump and Republicans in Congress to pass gun safety laws. Feeling pressure after a series of mass shootings this year, major retailers like Walmart and Dick's Sporting Goods have stopped selling some ammunition and guns while others have asked customers to stop openly carrying weapons in their retail stores.
