Washington - In his waning hours as a civilian Tuesday, president-elect Barack Obama sought the spiritual solace of church in a Washington thrumming with the happy cheers of human masses.
At noon (1700 GMT), Obama will become commander-in-chief of the US military as the first black US president, when he must tackle the unprecedented challenges of two wars and plummeting economy.
Following inaugural tradition, Obama, 47, and his wife Michelle, 45, dressed in a yellow sheath and matching coat, left Blair House, where White House guests stay, to attend services at nearby St John's Episcopal Church.
