A valedictorian’s speech on the Israel-Hamas war has sparked controversy, prompting condemnation from the dean of the University of Manitoba’s medical school and the billionaire American son of a major donor to say it “dishonoured the memory of my father” and “disrespected and disparaged Jews as a whole.”

Ernest Rady, who was born in Winnipeg, and is the son of Maxwell Rady, a Jewish refugee from Russia who studied at the university, said in a letter sent Monday to the school that he was “hurt and appalled” by the speech. The University of Manitoba’s medical school is now called the Max Rady School of Medicine.
