Three years ago today, a lone gunman took the lives of 14 students and three educators at Marjory Stoneman Douglas High School in Parkland, Florida. In seconds, the lives of dozens of families, and the life of an American community, were changed forever.

For three years now, the Parkland families have spent birthdays and holidays without their loved ones. They’ve missed out on the experience of sending their children off to college or seeing them on their first job after high school. Like far too many families, they’ve had to bury pieces of their soul deep within the Earth. Like far too many families — and, indeed, like our nation — they’ve been left to wonder whether things would ever be okay.

These families are not alone. In big cities and small towns. In schools and shopping malls. In churches, mosques, synagogues, and temples. In movie theaters and concert halls. On city street corners that will never get a mention on the evening news. All across our nation, parents, spouses, children, siblings, and friends have known the pain of losing a loved one to gun violence. And in this season of so much loss, last year’s historic increase in homicides across America, including the gun violence disproportionately devastating Black and Brown individuals in our cities, has added to the number of empty seats at our kitchen tables. Today, as we mourn with the Parkland community, we mourn for all who have lost loved ones to gun violence.

Over these three years, the Parkland families have taught all of us something profound. Time and again, they have showed us how we can turn our grief into purpose – to march, organize, and build a strong, inclusive, and durable movement for change.

The Parkland students and so many other young people across the country who have experienced gun violence are carrying forward the history of the American journey. It is a history written by young people in each generation who challenged prevailing dogma to demand a simple truth: we can do better. And we will.

This Administration will not wait for the next mass shooting to heed that call. We will take action to end our epidemic of gun violence and make our schools and communities safer. Today, I am calling on Congress to enact commonsense gun law reforms, including requiring background checks on all gun sales, banning assault weapons and high-capacity magazines, and eliminating immunity for gun manufacturers who knowingly put weapons of war on our streets. We owe it to all those we’ve lost and to all those left behind to grieve to make a change. The time to act is now.
