>> 7,000 colorful pairs of shoes were placed on the U.S. Capitol lawn by gun control activists on Tuesday, each pair meant to symbolize a child killed by gunfire in the United States since the Sandy Hook massacre. Tom Mauser says his son, Daniel Mauser, was wearing these white sneakers when he was gunned down years before Sandy Hook.
A victim of the Columbine school shooting, when 14 students and one teacher died, including the teenage killers.>> Daniel had mentioned, to me, in a conversation, he asked me a question. Did you know there were loopholes in the Brady Bill? That's the national law that requires background checks be conducted for all sales.
Then he was killed with a gun that was purchased through one of those loopholes.>> The powerful makeshift memorial comes just one day before students across the country plan to walk out of their classrooms in solidarity for 17 minutes to honor the 17 victims of the Parkland, Florida, high school shooting.
But efforts in Washington to change federal laws are waning despite an energized movement by young people demanding improved gun control. Reuter's correspondent Ian Simpson is reporting on the story.>> There have been no indications of major efforts to get gun control legislation through Congress. And the White House has also backed off President Trump's vows to raise the age for which people can buy guns in the United States.
So they're hoping that this will be able to generate momentum to enact gun control legislation.>> But there is some momentum at the state level. After weeks of pleading from survivors and the victims' families Florida Governor Rick Scott signed sweeping gun control legislation on Friday. The National Rifle Association immediately filed a federal lawsuit against the state.
