“I condemn in the strongest possible terms the racist activity taking place at the University of Pennsylvania.

It is heartbreaking to see this type of activity here in the birthplace of our democracy and the city of brotherly love. I urge the Philadelphia Commission on Human Relations to investigate and hold all responsible parties accountable for this disgusting behavior.”
