OKLAHOMA CITY (AP) — Black community and political leaders are calling on President Donald Trump to at least change the date of an Oklahoma rally kick-starting his return to public campaigning, saying that holding the event on Juneteenth, the day that marks the end of slavery in America, is a “slap in the face.”

California Sen. Kamala Harris and Tulsa civic officials were among the black leaders who said it was offensive for Trump to pick that day — June 19 — and that place — Tulsa, an Oklahoma city that in 1921 was the site of a fiery and orchestrated white-on-black attack.

The Trump campaign was aware in advance that the date for the president’s return to rallies was Juneteenth, according to two campaign officials, who were not authorized to speak publicly about internal discussions and spoke on condition of anonymity.

The campaign officials said the Trump campaign picked Oklahoma because arrangements could be made quickly, for a variety of reasons: Oklahoma has a Republican, Trump-friendly governor; the state is not seeing huge numbers of coronavirus cases; and the arena was “turn-key” and could easily be opened for the rally.

And on Wednesday, the same day Tulsa Mayor G.T. Bynum welcomed news of Trump’s rally pick as evidence of the city’s progress against COVID-19, Bynum apologized for remarks about a 2016 police killing of a black man.
