Dana White tells TMZ Sports … the UFC will donate $1 million to help the victims affected by the Las Vegas shooting. 
The UFC honcho said Vegas is his town — it’s where UFC is based and where he lives — and he feels it’s his duty to help the city recover in any way he can. 
White is calling on other Vegas moguls to pony up some dough as well — and wants people who live outside the city to know there’s one big way they can truly help out.
