“This is more about scoring political points with this president than the health of their citizens,” Mr. Turner said.
On Saturday, the twin sister of a man shot and killed by a police officer in 2016 said Mr. Trump’s visit to the city was an affront to her family and to the memory of the hundreds of African-Americans who died in the 1921 riot.
In 2016, a police officer shot and killed her brother Terence Crutcher, 40, a black motorist who was walking away from his vehicle with his hands up. The confrontation was captured on video, and led to the officer, Betty Jo Shelby, being charged with first-degree manslaughter in the death of Mr. Crutcher.
Officer Shelby was later found not guilty of manslaughter.
Tiffany Crutcher, Mr. Crutcher’s sister, said in an interview that she and her brothers are descendants of a survivor of the 1921 massacre, Rebecca Brown Crutcher.
“As an African-American and a descendant of the survivor of the worst domestic terror act against black people, it’s a slap in the face,” Ms. Crutcher said of Mr. Trump’s visit, as she sat at the Vernon A.M.E. church. “We know the residual effects that come out of his rallies — the rhetoric, the spew, the hate, the bigotry. All of those things are simply a recipe for a disaster for Tulsa, Oklahoma.”
A high-ranking Tulsa police official said on a talk-radio show recently that officers are “shooting African-Americans about 24 percent less than we probably ought to be, based on the crimes being committed.” And on June 4, two black teenagers were confronted by the police for jaywalking and wrestled to the ground and handcuffed, all of which was captured on video.
“We were already triggered,” Ms. Crutcher said. “For Donald Trump to come and fuel the fire with his supporters, it’s simply unacceptable. We are outraged.”
