AP - Barack Obama stood at the threshold of the White House on Monday, summoning fellow Americans to join him in service as tens of thousands flocked to the nation's capital to celebrate his inauguration as the first black president. "Tomorrow we will come together as one people on the same Mall where Dr. King's dream echoes still," said the president-elect, invoking the memory of the Rev. Martin Luther King Jr. on the national holiday in his honor.
