Dana White says former President Donald Trump won't be able to hide from the spotlight at UFC 264, because he'll be right next to the octagon ... where fans can loudly cheer and jeer him.
The UFC honcho joined us Friday on "TMZ Live" to pump up Conor McGregor and Dustin Poirier's third fight ... and, in the process, he settled a debate about where Trump will sit Saturday night in Vegas.
It's the first major sporting event Trump's attending since leaving the White House -- and with all that's happened since he lost the election, it's a good bet (even in Vegas) the ex-prez will hear plenty of boos.
