The U.S. president has repeatedly asked the two Mideast allies to take in two million Palestinians from Gaza. Both Egypt and Jordan have been trying to offer Mr. Trump help in other ways.

The Saudi media reported that Crown Prince Mohammed bin Salman had spoken with President Trump, who made the kingdom the first stop on his first overseas presidential trip in 2017.

The two Mideast powerhouses have been trying to block the rise of Islamist groups in the region for two decades. The rebel takeover in Damascus will test that approach.
