There are no words to describe how I felt when I saw the news this morning that a gunman opened fire at Pulse Nightclub in Orlando last night, killing at least 50 and wounding at least 53 others: the deadliest mass shooting in United States history.

My heart breaks for the mothers, fathers and families who are being notified by law enforcement that their loved ones are battling for their lives in the hospital or will never make it home. I know so horribly what they’re going through.

We stand with them. Our hearts are in Orlando right now, but we must stand together and work for an end to gun violence in America. We must work tirelessly until we are able to live in a world that is safer for all.

There are reports this horrific tragedy is related to domestic terrorism and could also be a hate crime, having taken place at a popular LGBT club during Pride Month. But what we already know to our very cores is Americans should be able to enjoy a night out, go to work and board the school bus without wondering if they might never return home again.

President Obama called the attack “a sobering reminder that attacks on any American, regardless of race, ethnicity, religion or sexual orientation, is an attack on all of us and on the fundamental values of equality and dignity that define us as a country.”

He’s right. We can’t go on like this. We can’t become numb or immune. Instead we must commit once again to work for an end to gun violence. We will work beyond our heartbreak, beyond ourselves, for a world that is safer for all.

We must reject helplessness and hopelessness – for those recovering, for those we lost, and for those who have to face tomorrow without their loved ones. We must work to ensure these lives were not lost in vain.

As our hearts break once again, our spirits remain strong.
