During his trip to Riyadh on Tuesday, President Donald Trump and Saudi Arabia’s de facto ruler, Crown Prince Mohammed bin Salman, signed more than a dozen agreements addressing each nation's armed forces, justice departments, and cultural institutions.

Tuesday's U.S.-Saudi agreements mark a win for 45th president, who has set a goal of reaching $1 trillion in U.S. investment by the Gulf nation. Since taking office, Trump has already secured $600 billion from the Crown Prince over the next four years. The investments span technology, defense, energy and other sectors including purchase commitments by the Saudis for American goods. 

Trump will also travel to Qatar and the United Arab Emirates before returning to Washington on Saturday.
