WASHINGTON (AP) - President Barack Obama says his second inauguration is a celebration of the country and its citizens, not the election results. Obama used a speech to hundreds of supporters at the National Building Museum Sunday night to remind the crowd that "what we're doing is celebrating each other and celebrating this incredible nation that we call home." He encouraged the crowd to enjoy the inauguration and said he needs them to work as hard as they can on issues important to them. Obama said the inauguration is a reminder that "there is something bigger than ourselves." He kept his comments brief and quipped that he has to save some of his lines for his speech Monday.
