That was President Bill Clinton, in a statement immediately after Columbine.

Later, he traveled to Littleton, Colorado, where he said:

What happened to you has pierced the soul of America. And it gives you a chance to be heard in a way no one else can be heard—by the president and by ordinary people in every community in this country. You can help us to build a better future for all our children...

You can reach across all the political and religious and racial and cultural lines that divide us. You have already touched our hearts. You have provoked Hillary and me and the vice president and Mrs. Gore to reach out across America to launch a national grassroots campaign against violence directed against young people. You can be a part of that. You can give us a culture of values instead of a culture of violence. You can help us to keep guns out of the wrong hands.

All of this was said more than 13 years ago.
