• Saudi Arabia is set to give President Trump a royal welcome on his first overseas trip in office this weekend.

A $100 billion-plus arms deal is meant to show a renewed U.S. commitment to the kingdom’s security. Mr. Trump’s son-in-law, Jared Kushner, intervened with Lockheed Martin to cut the cost of the Saudi purchase.

Mr. Trump is to give a speech about Islam and attend a summit meeting with leaders from Muslim countries. On the guest list is Sudan’s president, who is accused of war crimes. Not invited are leaders from Syria and Iran.
