“We are at a crossroads in Egypt and we need a clear vision,” said the 64-year-old resident of San Marino, just south of the Caltech campus in Pasadena.

Suleiman serves on President Barack Obama’s council on science and technology, and is a celebrated native son in Egypt. He has lived in the United States since the 1970s but travels home often, his wife Dema Zewail told the Pasadena Star-News.

She said her husband’s role in the saga is a call of duty “above and bigger than we need to respond to,” she told the newspaper. “You have to disassociate yourself from the person you are, living in Pasadena.”
