Thousands of people descended on Chicago’s downtown to demand action from Congress to tighten the nation’s gun laws.
The group, a cohort that included Moms Demand Action for Gun Sense in America, walked from Federal Plaza, stopping at Daley Plaza in the Loop, before walking to Trump Tower, a symbolic location as the President maintains residence in Washington.
Estimates were that as many as 3,000 people showed up.
Participants held up signs, many of them directed at the National Rifle Association, a national advocacy group for gun rights.
There were also a number of children in attendance.
Preeta Swaminathan and Shivani Jambunathan were among them.
Preeta, in the seventh grade said she will soon begin practicing shooting drills at school.
“That makes me sad and also a little bit afraid because these things have never happened before and now that's it's starting, that means these things have become even worse,” she said.
Shivani, in the fifth grade, said she didn’t want to see similar shootings.
“We hope that there aren't any more mass shootings and that people don't buy guns to kill a lot of people,” she said.
The group said they wanted Congress to enact tougher laws when it comes to accessing guns.
In the Florida shooting, the accused gunman used a semi-automatic AR15-style rifle.
