Trump's UFC event at the White House is going ahead, but most Americans hate it and his approval keeps sinking.

• A 92-foot stadium called "the claw" was built on the White House lawn for a UFC fight night.
• Only 16% of Americans think it's appropriate, and even among Republicans just 31% approve.
• 60% say the White House is out of touch with regular people, rising to 80% of independents.
• A lawsuit claims Trump and the UFC are using public property for private profit through paid sponsorships and ads.
• An Iran deal is close but not signed, and the two sides remain far apart on sanctions, nuclear material, and frozen money.

Outlook: A judge could block parts of the event, and the deepening unpopularity points to more trouble ahead for Trump.
