IIRC, that is the honoree, Palestinian terrorist supporter Rhashid Khalidi, and his wife Mona, who was founder and CEO of some Arab organization in Chicago.
This was the farewell dinner for him - he was leaving Univ of Chicago and going to Columbia. He was buds with Edward Said at NYU, another charming anti Israel hatemonger.
Nope, that photo is of the Saids with the Obamas at a 1998 event for which the late Edward Said was the keynote speaker.
Another gathering of anti-American radicals, with Obama right in the heart of things.......
