President Joe Biden signed a bill into law to make lynching a federal hate crime, more than 100 years after such legislation was first proposed.
The Emmett Till Anti-Lynching Act is named after the black teenager whose killing in Mississippi in the summer of 1955 became a galvanising moment in the civil rights era. His grieving mother insisted on an open casket to show everyone how her son had been brutalised.
Biden acknowledged the long delay during remarks in the Rose Garden to lawmakers, administration officials and civil rights advocates, stressing how the violent deaths of black Americans were used to intimidate them and prevent them from voting simply because of their skin colour.
"Thank you for never giving up, never ever giving up," the president said. "Lynching was a pure terror to enforce the lie that not everyone, not everyone, belongs in America, not everyone is created equal."
