President Obama called for unity on 9/11, saying in his weekly radio address, "If there is a lesson to be drawn on this anniversary, it is this: We are one nation—one people—bound not only by grief, but by a set of common ideals.” The president urged Americans to help people in need and give back to their communities. Obama will lay a wreath at the Pentagon Saturday to commemorate the ninth anniversary of the terror attacks, while Michelle Obama will join Laura Bush for a ceremony in Shanksville, Pennsylvania, where passengers prevented terrorists from using a fourth plane to attack civilians. Vice President Joe Biden attended a service at Ground Zero. The memorial services come amid a wave of anti-Muslim sentiment in the U.S., and Obama urged people to not let a few “stoke bitterness” and “blind us to what we have in common… We do not allow ourselves to be defined by fear, but by the hopes we have for our families, for our nation, and for a brighter future." The Republicans’ radio address echoed Obama’s, with Sen. Jon Kyl (R-AZ) calling for a recapturing of unity.
