The brutal killings of Ahmaud Arbery, Breonna Taylor and George Floyd have left me despondent, but also determined. Despondent and deeply angry that America cannot rid itself of the disease of racism and violence, and that police and prosecutors too often inflict pain on communities rather than protecting them. But determined not to let this moment pass without an uncompromising demand for justice on behalf of the victims’ families. I support House Judiciary Committee Chairman Jerry Nadler’s urgent request to the U.S. Department of Justice to investigate the prosecutors in the Ahmaud Arbery case and to open misconduct inquiries into the Louisville and Minneapolis police departments. Condolences and expressions of outrage are not enough. We must take swift action.
