Sherry Gamble Smith, the president of the Black Wall Street Chamber of Commerce, named after the neighbourhood that was attacked, said, "Tulsa is outraged."

At the rally itself, the Trump campaign has not announced any social distancing plans, though spokesman Tim Murtaugh said, "There will be health precautions".
