President Donald Trump is expected to reach an agreement with Saudi Crown Prince Mohammed bin Salman that would allow the kingdom to purchase F-35 stealth planes, according to an administration official.

The official, who spoke on condition of anonymity to discuss details not yet made public, said Trump and the crown prince — known as MBS — intend to sign economic and defense agreements during a visit to the White House scheduled for Tuesday. Those agreements will also include a deal on purchases of liquefied natural gas, the official added, without providing more details.
