RIYADH, Saudi Arabia – President Donald Trump, in the first stop of his maiden trip abroad, received a regal welcome Saturday in Saudi Arabia, feted by the wealthy kingdom as he aims to forge strong alliances to combat terrorism while pushing past the multiple controversies threatening to engulf his young administration.

He later was given a tour of one of Riyadh's most opulent palaces and sat through an elaborate signing ceremony in which, one by one, the Saudis agreed to military deals with the U.S.
