Black community enraged by the custodial killing of George Floyd 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."

Trump campaign officials discussed in advance the possible reaction to the Juneteenth date, but there are no plans to change it despite fierce blowback. California Sen. Kamala Harris and Tulsa civic officials were among the 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.
