Gregory Porter, according to his Facebook profile, is a student at Drexel University and graduated in 2010 from La Salle College High School, a Catholic prep school, in Wyndmoor, Penn. He was an active participant on the debate team focusing on policy debate, according to LaSalle’s Web site.

Luke Gates, a student at Indiana University, updated his current city of residence to Cairo on Aug. 31, according to his Facebook profile. He lists al-Jazeera English and WikiLeaks as interests.

On Twitter, Gates wrote often of his experiences in Tahrir Square, and said he wanted to die in Egypt. He has a Google profile here.

Derrik Sweeney, a Georgetown University student, was an intern for Rep. Blaine Luetkemeyer (R-Mo.) from February to May 2011. Georgetown University says it is in contact with Sweeney’s parents, the American University in Cairo, and the U.S. State Department. His father says he was “caught up in the hype” of Egypt protests.

Students at the American University Cairo reported that the campus would close early today “due to high likelihood of traffic congestion related to protests anticipated later.”
