Those of us who have the privilege to serve this country have an obligation to do our job as best we can. We come from different parties, but we are Americans first. And that's why disagreement cannot mean dysfunction. It can't degenerate into hatred. The American people's hopes and dreams are what matters, not ours. Our obligations are to them. Our regard for them compels us all, Democrats and Republicans, to cooperate, and compromise, and act in the best interests of our nation - one nation, under God, indivisible with liberty and justice for all.

Join our campaign to stop this violence.
