Why not? He was a part of a pretty radioactive network of people. I doubt that he just happened to hang with Epstein by mere coincidence, and it does raise some questions about how much Sheryl knew about it.

I think it's very silly to suggest that Sandberg would have known anything at all about Summers personal life a decade before he had dealings with Epstein, simply because he was an undergraduate adviser to her. He was already one of the most famous economists in the country in the late 1980s, when that happened.
