Dana White confirms to TMZ Sports ... he WILL be speaking at the Republican National Convention next week to talk about his relationship with Donald Trump.
The UFC honcho has been very vocal about his support for Trump -- and previously appeared on the "TMZ Sports" TV show on FS1 and explained why he's got Donald's back no matter what.
As for White's RNC speech -- Dana says it won't be political ... but rather, "It will be about my relationship with Trump and the Trump that I know."
