Jackson is reciting a prayer with the refrain, "It's healing time. It's hope time. It's Hillary time."
He's getting the crowd excited; they're now chanting with him.
Jackson immediately says, "Tonight, I stand proudly in support of the next President of the United States, Hillary Clinton. And let me also congratulate Bernie Sanders for energizing this campaign season with ideas and hope."
The White House just released excerpts of President Barack Obama's speech to the Democratic National Convention later tonight.
