It was supposed to be an opportunity for Barack Obama to soothe the tensions that still simmered between Hillary Clinton's supporters and his own. In July, the senator had secured the Democratic nomination and planned to use a New York City fundraising event to solicit donations to help pay off Clinton's millions of dollars in campaign debt. But Obama gave a 32-minute speech that never mentioned the debt and started walking off to Stevie Wonder's "Signed, Sealed, and Delivered," before realizing his error. Rushing back on stage, Obama said, "Hold on a second, guys! I was getting all carried away!" He then solicited the help, and doubts about whether fences had been mended were put to rest months later, when Clinton agreed to serve as Obama's secretary of state.
