Students, teachers, parents and their allies will converge on the nation's capital next weekend to rally for gun control and school safety measures in the wake of last month's shooting in a Florida high school.
Thousands of people from across the country are expected to participate in the "March for Our Lives," organized by students of Marjory Stoneman Douglas High School in Parkland, Florida, where a gunman killed 17 people and injured others on Valentine's Day. The accused shooter, 19-year-old Nikolas Cruz, was a former student at the school and was armed with an AR-15-style rifle he had legally purchased a year ago, authorities said.
Now, students around the country -- using the slogan "Never Again" -- are calling on lawmakers to make schools safer and enact tougher gun control laws, such as prohibiting the sale of high-capacity magazines and banning the high-powered, highly-lethal assault-style weapons often used in mass shootings.
Here's everything you need to know about the upcoming "March for Our Lives."
When is the march?
"March for Our Lives" will begin at noon ET on Saturday, more than five weeks after the deadly school shooting.
There have been other events in support of the shooting survivors, including a National School Walkout on March 14 that lasted for 17 minutes to honor those killed a month earlier in Parkland and to protest gun violence across the country.
Where is the march?
The main "March for Our Lives" event will take place in Washington, D.C., beginning on Pennsylvania Avenue between 3rd Street NW and 12th Street NW.
But there are hundreds of satellite marches, or "sibling marches," planned for the same day around the world. Each sibling march is an independent, student-led initiative, according to the "March for Our Lives" official website.
There are sibling marches planned in cities including Los Angeles, Chicago, New York City, Boston, Ottawa, Buenos Aires, Madrid, Paris, Dublin, London, Berlin, Stockholm, Rome, Tel Aviv, Mumbai, Hong Kong, Tokyo and Sydney, to name just a few.
Who's supporting the event?
Countless people, including a number of celebrities, have voiced their support for the march by announcing their plans to participate or donating to the movement's GoFundMe page, which has raised over $3.3 million in just 24 days. Half of the funds raised via the crowdfunding platform will go toward the March for Our Lives Action Fund, which will cover expenses associated with the March 24 event in Washington, D.C.
The other half will be given to the victims and their families of the Feb. 14 school shooting via the Broward Education Foundation.
Actor George Clooney and his wife, Amal, a human rights lawyer, gave $500,000 to "March for Our Lives" and said their family will be at the event in Washington, D.C.
“Amal and I are so inspired by the courage and eloquence of these young men and women from Stoneman Douglas High School," George Clooney said in a statement on Feb. 20. "Our family will be there on March 24 to stand side by side with this incredible generation of young people from all over the country, and in the name of our children Ella and Alexander, we’re donating 500,000 dollars to help pay for this groundbreaking event. Our children’s lives depend on it."
Media mogul Oprah Winfrey announced via Twitter that she will match the Clooneys' donation. She tweeted, "George and Amal, I couldn’t agree with you more. I am joining forces with you and will match your $500,000 donation to ‘March For Our Lives.’ These inspiring young people remind me of the Freedom Riders of the 60s who also said we’ve had ENOUGH and our voices will be heard."
Many celebrities, including singers Harry Styles, Mariah Carey and Justin Bieber, have also shown their support by signing a petition created by the "March for Our Lives" organizers that calls for action to end gun violence and protect schools.
David Hogg, a student at Marjory Stoneman Douglas High School, announced on CNN that singers Ariana Grande, Jennifer Hudson, Miley Cyrus and Demi Lovato will be marching alongside him and the other organizers in Washington, D.C.
Why are people marching?
The "March for Our Lives" organizers explain on the official website that they support the constitutional right of law-abiding U.S. citizens to bear arms, but the recent surge of mass shootings, particularly at schools, calls for an honest discussion about guns.
So students, teachers and their supporters will take to the streets because they "will no longer risk their lives waiting for someone else to take action to stop the epidemic of mass school shootings that has become all too familiar," the organizers say.
"Not one more. We cannot allow one more child to be shot at school. We cannot allow one more teacher to make a choice to jump in front of a firing assault rifle to save the lives of students," the organizers say in their online mission statement. "In the tragic wake of the seventeen lives brutally cut short in Florida, politicians are telling us that now is not the time to talk about guns. March For Our Lives believes the time is now."
