UPDATE 4-Biden honors Tulsa race massacre survivors 100 years on Reuters 8 hrs ago By Jeff Mason TULSA, Okla., June 1 (Reuters) - Joe Biden on Tuesday became the first sitting U.S. president to visit the Tulsa, Oklahoma, site where hundreds of Black Americans were massacred by a white mob in 1921, as he marked the country's legacy of racial violence. Biden oversaw a moment of silence for the victims after meeting with three people who lived in the district during the massacre - Viola Fletcher, Hughes Van Ellis and Lessie Benningfield Randle - and toured a museum dedicated to the incident. "For much too long the history of what took place here was told in silence," Biden said.
