Before Trump began his visit to Saudi Arabia, Qatar and the United Arab Emirates, his sons Eric and Donald Jr. had already traveled the Middle East extensively in recent weeks. They were drumming up business for The Trump Organization, which they are running in their father’s stead while he’s in the White House.

Mr. Trump has few meetings directly about pressing geopolitical challenges. Instead, he’s in the Persian Gulf to make deals.

President Donald Trump wrapped up the first day of his three-nation tour of the Middle East today in Riyadh. He thanked the Kingdom of Saudi Arabia for a warm welcome and said the US-Saudi partnership has never been stronger.
