Facebook CEO Mark Zuckerberg and COO Sheryl Sandberg are about to interview President Barack Obama in a live town hall from the company's headquarters. Update: although the live event is over, we have pics of the event, Obama and Zuckerberg here.

The discussion will be carried to millions of people via Facebook Live, the social network's official streaming video/TV channel. The town hall, which begins at 4:45 p.m. EST/1:45 p.m. PST, will feature Zuckerberg and Sandberg asking Obama about the economy, funding innovation and the future of technology. In addition, Obama will answer questions submitted via the web. And Mashable will be there, covering the president's remarks in person.

Facebook has welcomed countless celebrities through its doors (Katy Perry comes to mind), but Obama is by far the highest profile public figure to ever walk through Facebook's doors. Just two months ago, Obama visited Silicon Valley to wine and dine with technology's most prominent figures, including Facebook's young CEO.

For your convenience, we've embedded the live video feed for today's conversation as well as a live Facebook Comments stream so you can opine about Obama's performance in real time.
