He professed his “unyielding faith in the decency and generosity of the American people” even as he acknowledged the Constitution’s unfinished work, the need to extend liberty and justice to all people. He criticized his pastor’s “incendiary language” that denigrated “both the greatness and the goodness of our nation,” and he denounced “the perverse and hateful ideologies of radical Islam.”
