Donald Trump Jr. and his brother, Eric Trump, are getting the early bird special at the UFC fight in New Jersey this weekend -- 'cause they showed up hours before the big bout.
President Trump's sons are sitting cage-side right now at the Prudential Center in Newark for the UFC on ESPN 5 event, where welterweights Colby Covington and Robbie Lawler are facing off for the main event. Colby personally invited DTJ and co. -- they're pals.
Sources connected to the event tell TMZ Sports that Don, Eric and their brood -- which appears to include Don's GF, Kimberly Guilfoyle and at least one kid -- arrived Saturday around 10 AM PT .
