On Monday's broadcast of CNBC's "Squawk Box," Anti-Defamation League CEO Jonathan Greenblatt reacted to students at Harvard University blaming Israel for being attacked by Hamas by stating that the school is "clearly not educating students" if they believe that "murder at scale is somehow legitimate," and "think it's okay to equivocate in the face of fascism." And stated that Harvard needs to revisit its entire core education.
