A watchdog group has filed a lawsuit attempting to halt the fight, noting the money that UFC stands to make off the event, and that Trump owns up to $50,000 of stock in the company that owns UFC.

The DOJ has responded, saying in part it would be too disruptive to halt an event a year in the making, and noting past presidents' White House events.

White House spokesperson Davis Engel insisted to NPR there are no conflicts of interest and added that Trump's assets are in a trust managed by his children.
