Donald Trump's invitation to address an association of black journalists - along with the group's shunning of Kamala Harris - has sparked outrage, resignations, and internecine fighting among its membership.

Trump is scheduled to take part of moderated discussion with the National Association of Black Journalists on Wednesday at their annual convention in Chicago. 

Meanwhile, the group declined an offer from Harris to appear for a virtual conversation. The vice president could not appear in person due to logistical reasons, including her attendance at the funeral of the late Rep. Sheila Jackson Lee in Texas. 

Adding fuel to the fire is a report the group tried to get a prominent Harris surrogate instead, such as Megan thee Stallion, Oprah Winfrey or Barack Obama. 

About 30 minutes before Trump was scheduled to speak, the NABJ announced they are in talks with Harris to appear either in person or virtually at some point in September. 

Trump reacted in fury to the news, noting he was told he had to fly to Chicago.

'They told me and Crazy Kamala Harris that you could not do this Event with ZOOM — It is not allowed or acceptable! She declined, and I am getting ready to land in Chicago in order to be there. Now I am told that she is doing the Event on ZOOM. WHAT'S GOING ON HERE?,' he wrote on Truth Social.

But it's the presence of Trump - who clashed with prominent black journalists when he was president - and the exclusion of Harris - who would be the first female black president if elected - that has members of the group publicly slamming the association and each other. 

Trump weighed in on Truth Social.

'Crazy Kamala disrespectfully refused to attend the National Association of Black Journalists Conference, but I am on my way to meet with them now in Chicago. Because of which, she'll probably end up doing, she has no choice, but remember—it is only for that reason!,' he wrote.
