The President of Colombia University believed with the chants of “Mahmoud Al -Hurra”

Claire Shibman, President of Columbia University, was screaming during the graduation ceremony on Tuesday, with the chants of “Mahmoud Al -Hur” that he heard her drowning.

Mahmoud Khalil, a graduate of the University of Colombia, was arrested by American immigration officials in March because of his role in pro -Palestinians protests on the campus. He is a permanent legal resident in the United States and has not been accused of a crime.

Mr. Khalil remains in detention in the United States while the official seeks to deport him.

President Donald Trump described the pro -Palestinian protests hostile to Semitism, but the student activists denied this.
