OKLAHOMA CITY (AP) – Black community leaders in Tulsa said they fear a large rally by President Donald Trump in the city this weekend could spark violence. Meanwhile, the state’s governor asked Trump not to visit the site of a race massacre where up to 300 black residents were killed by white mobs in 1921. Tens of thousands of Trump supporters are expected in Tulsa Saturday for the first of a series of rallies across the country. The rally at the 19,000-seat BOK Center would overlap a two-day local celebration of Juneteenth, which marks the end of slavery in the country.
