Thousands of demonstrators took to the streets on Saturday for the annual March for Our Lives rally, a nationwide protest against gun violence.
The non-profit group, founded by survivors of the 2018 Parkland shooting, told NBC News there were about 450 rallies planned across the United States, including in cities like Chicago; Los Angeles; NYC; Detroit; and Washington, D.C. The demonstrations come amid renewed calls for tighter gun control measures, as the nation continues reeling from a series of mass shootings.
