Tim Kaine shows off his Democratic nomination form

Hi everyone, @TimKaine here. I'm taking over Hillary's Instagram for the day—my first day on the trail as her running mate! It's the honor of a lifetime to join Secretary Clinton in making the case for an America where everyone, no matter where they come from, how much money they have, what they look like or who they love, has a shot at success.

First order of business: filling out the official paperwork to be nominated at the @DemConvention in Philadelphia this week. -TK
