Ross Glick, a pro-Israel activist who previously shared a list of campus protesters with federal immigration authorities, said that he was in Washington, D.C., for meetings with members of Congress during the Barnard library demonstration and discussed Khalil with aides to Sens. Ted Cruz and John Fetterman who promised to “escalate” the issue. He said that some members of Columbia’s board had also reported Khalil to officials.

“This unfolded very quickly because it was obvious,” Glick said in an interview Monday.“Everybody was upset,” he recalled of his meetings on the Hill. “The guy was making it too easy for us.”
