The role of citizen in our democracy does not end with your vote.

On Memorial Day we come together as Americans to let these families and veterans know that they are not alone. We give thanks for those who sacrificed everything so that we could be free. And we commit ourselves to upholding the ideals for which so many patriots have fought and died.

Several Americans, unjustly detained by Iran, are finally coming home. In some cases, these Americans faced years of continued detention, and I've met with some of their families. I've seen their anguish, how they ache for their sons and husbands. I gave these families my word. I made a vow that we would do everything in our power to win the release of their loved ones, and we have been tireless.
