DUBAI, United Arab Emirates — Two of U.S. President Donald Trump’s sons are in the United Arab Emirates for an invitation-only ceremony to open the Trump International Golf Club in Dubai.

Eric and Donald Jr. attended a private luncheon Saturday afternoon with business partners of Hussain Sajwani, the billionaire who runs DAMAC Properties, the developer that partnered with Trump on the golf course.

Photographs shared on social media by a real estate broker who attended the luncheon showed the two Trumps there.

Trump’s two sons, who now run the Trump Organization, are scheduled to attend a gala at the golf course Saturday night.

The ceremony in the Mideast city-state home to the world’s tallest building marks the first major event abroad that the two Trump sons will attend together since their father’s inauguration.
