Update 2:30 p.m. 'Hoping For Unity':
With the ceremony at the Capitol complete, spectators looked ahead to their hopes for the next four years. Speaking to NPR's Tom Dreisbach, here's what some in the crowd had to say:
"I'm looking for Washington to start getting along. I mean nobody's working together. And both sides have got to give a little bit and they've got to come to some agreement on some things."
