The schedule via CNN:

The most important order of business: Democrats will officially make Clinton the first female presidential nominee from a major party with the roll call vote.

Later in the evening, Bill Clinton ...will make the case for his wife's election.

The theme of the day, though, will be driven by the "Mothers of the Movement" -- a group of speakers that includes the mothers of Eric Garner, Michael Brown, Sandra Bland and more, all men and women who died in police custody or as a result of police actions. Trayvon Martin's mother, whose son died at the hands of neighborhood watch volunteer George Zimmerman, will also speak.
