He was welcomed by Saudi Arabia's de facto ruler, Crown Prince Mohammed bin Salman, after Air Force One landed in Riyadh. Trump and the crown prince are to hold talks on U.S. efforts to dismantle Iran's nuclear program, end the war in Gaza, hold down oil prices and more.
Trump is also expected to be feted by the crown prince with a formal dinner and a gathering of members of the Gulf Cooperation Council — made up of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates — later on Tuesday.
