Wada’an Mahmoud Khalil

If you are on Twitter, you no doubt have seen stories in the trending column about a person named Mahmoud Khalil. He is a graduate student at Columbia and an anti-Israel protestor, popular in that subculture. The Trump admin arrested him on the grounds that he is a foreigner making a nuisance of himself. He is the worst sort of nuisance, the sort that publicly agitates against Israel.
