Protests over the death of George Floyd in Minneapolis police custody have spread to other cities across the United States. In New York City, protesters defied the coronavirus prohibition on public gatherings Thursday, clashing with police, while demonstrators blocked traffic in downtown Denver and downtown Columbus. A day earlier, demonstrators had taken to the streets in Los Angeles and Memphis. Meanwhile, a Mississippi mayor whose remarks about Floyd’s death sparked outrage is resisting calls to resign, including from his own town’s board of aldermen.
