A new coalition of celebrities and activists, including actor Alyssa Milano and Parkland student David Hogg, announced plans Friday to take on the National Rifle Association and elected officials who accept money from the powerful gun advocacy group.

Hundreds of thousands of students and parents from Newtown, Conn., to Columbine, Colo., descended on Washington or participated in sister rallies across the United States on Saturday to condemn the scourge of gun violence and call on lawmakers for substantive change

Until recently, advocates for gun control hadn’t realized what their movement was missing: fearless, outraged teen-agers. On Saturday morning, in Washington, D.C., students and parents gathered to protest the lenient gun laws that allow for endless mass shootings in America. Many had orange price tags dangling from their wrists: $1.05, the amount the National Rifle Association donated to the Republican senator Marco Rubio, divided by the number of students in Florida, the state he represents. A massive sound system broadcast pop songs: Kesha’s “Tik Tok,” Britney Spears’s “Toxic,” the Killers’ “Mr. Brightside.” The mood was celebratory, but determined.

Lauren Milgram has a mission. The sweet and funny, shy yet confident, 12-year-old will join an anticipated hundreds of thousands of people at the March for Our Lives in Washington on Saturday.

The screams for change by survivors of a school shooting are very personal for her. Because for almost half her life, Lauren has been a survivor, too.

After the latest mass shooting incident that killed 17 students and teachers at Parkland Florida's Marjory Stoneman Douglas High School on Feb. 14, expectations were that interest in yet another tragic story of gun violence would soon fade from the headlines. But something is different this time. Student survivors of the Parkland massacre refused to let their grief and trauma stop them from speaking out and becoming active in the campaign to rein in gun violence.

The Obama administration has announced new actions to curb gun violence in the United States. On Friday, the President outlined a strategy pushing “smart gun” technology. Eric Milgram, father of two Newtown survivors, joins MSNBC’s Ayman Mohelydin to share his opinion on the “smart gun” push.
