WASHINGTON (AP) — President Joe Biden’s national security adviser Jake Sullivan is traveling to Saudi Arabia. Sullivan is to meet with Crown Prince Mohamed bin Salman as the U.S. presses for a cease-fire in the yearslong war between the kingdom and Houthi rebels in Yemen. That’s according to two senior administration officials who spoke on the condition of anonymity. Sullivan travels Monday and will be the highest-ranking Biden administration official to visit Saudi Arabia. The White House has largely steered clear of the crown prince since making public a CIA report that showed he likely approved the killing of Washington Post columnist and Saudi critic Jamal Khashoggi.
