Billionaire Leon Cooperman, who's donated millions to Columbia University, had some choice words after students and professors at his alma mater rallied in support of Hamas.

"I think these kids at the colleges have shit for brains," Cooperman said Wednesday on Fox Business. The billionaire investor said he will suspend his donations to Columbia after the university refused to fire Professor Joseph Massad, who supported the rally and called Hamas's terrorist attack this month "awesome."
