Sawyer made the announcement, not surprisingly, on her Facebook page and is soliciting questions for Zuckerberg from her fans.

Big Announcement: On Wednesday I’ll be sitting down with Mark Zuckerberg, creator and founding brain of Facebook. I want to bring questions from you, so send them my way and let’s see what happens.

According to an ABC News press release, Zuckerberg will give Sawyer a tour of the facility before sitting down for a one-on-one interview. The interview will air Wednesday, July 21 on “World News,” which will originate from Palo Alto, CA that evening. Additional excerpts will be featured on other ABC News programs and platforms.

Sawyer has another exclusive interview the day before, with new UK Prime Minister David Cameron.
