A cornerstone event of the Tulsa Race Massacre commemoration in Oklahoma was abruptly canceled because lawyers representing survivors and descendants demanded a higher fee for their participation in the event than had been originally agreed upon, a commission official said. Legal representatives for the three living survivors approached the Tulsa Race Massacre Centennial Commission about including them in the “Remember and Rise” occasion in return for $100,000 each and a $2 million seed gift to a reparations coalition fund, state Sen. Kevin Matthews, chairman of the commission, said in a Friday press conference.
