Saudi social media users have uploaded images showing the streets of Riyadh illuminated by the color of the American flag or billboards showing the faces of Trump and Saudi King Salman.
According to the Washington Post, Trump will use his meeting with Muslim leaders to lay out his vision for a new regional security architecture described by White House officials as an "Arab NATO" to confront terrorism and Iranian ambitions in the region. The Post says the visit came about after behind-the-scenes negotiations between White House senior adviser Jared Kushner and Saudi Deputy Crown Prince Mohammed bin Salman. Trump will also announce one of the largest weapons deals in history, between $98 billion and $128 billion in arms sales to Saudi Arabia.
After his visit to Saudi Arabia, President Trump will head to Israel and the Vatican, the three major monotheistic religions, adding these stops to the previously announced visit to NATO and G7 summits in Brussels and Sicily later this month.
