Conor McGregor is known for his brash statements about opponents, and seemingly everyone else. But when approached by TMZ and asked about Holly Holm's major upset win over Ronda Rousey at UFC 193, he was complimentary towards both women.

"Very tough fight. Holly fought a great fight. I have much respect. This is the fight business. These things happen. Ronda will be back. True champions come back. And congratulations to Holly, the new champion."

...

"Defeat is the secret ingredient to success," he said in regards to Rousey. "True champions can conquer that, overcome it and come back. So I wish her all the best and that's it."

Holm defeated Rousey by knockout in the second round on that night. Shortly thereafter, republican presidential candidate Donald Trump decided to capitalize on the event by tweeting about Rousey, and he wasn't very nice.

Glad to see that @RondaRousey lost her championship fight last night. Was soundly beaten - not a nice person! — Donald J. Trump (@realDonaldTrump) November 16, 2015

When informed about that, McGregor was blunt in his assessment of the business mogul:

Donald can shut his big, fat mouth. I don't give a f**k about Donald Trump."

McGregor returns to the octagon at UFC 194 next month in a title unification bout against Jose Aldo.
