"Is that what a black man is worth, 20 dollars?" George Floyd's brother Philonise asked the U.S. Congress in an emotional plea to pass reforms that reduce police brutality. "This is 2020. Enough is enough," he said a day after burying his brother in Houston.

Floyd's death, which has led to a global protest against racial injustice, began with a report of a counterfeit 20 U.S.-dollar bill that a storekeeper said he tried to pass to buy cigarettes.
