The chairman of Temple University’s board came out firing Friday against professor Marc Lamont Hill for a speech he made at the United Nations this week criticizing Israel and its treatment of Palestinians.

Patrick O’Connor called Hill’s remarks, which cost him his position as a commentator on CNN, “lamentable” and “disgusting.”

“It should be made clear that no one at Temple is happy with his comments,” said O’Connor, a prominent Philadelphia lawyer. “Free speech is one thing. Hate speech is entirely different.”

In the speech Wednesday as part of the U.N.’s International Day of Solidarity with the Palestinian People, Hill, a Philadelphia native who holds an endowed chair in Temple’s Klein College of Media and Communications, accused Israel of rampant discrimination against Palestinians.
