Obviously it will be on your local PBS affiliate. However, it will also be streamed from PBS online:
Three ways to watch online:
Watch it live. The Democratic Forum will be simultaneously webcast on PBS.org from 9pm-10:30pm (Eastern) on June 28th.
Watch it later. Video of the Democratic and Republican Forums will be archived for on-demand viewing here on PBS.org.
Take it with you. Download both Forums on your iPod or other portable device by subscribing to the Tavis Smiley podcast or visiting iTunes at the Apple Music Store.
I’m assuming the stream will be available here: All-American Presidential Forum on PBS
We’ll also have the video archived after it airs.
