U.S. Vice President Joe Biden is leading an American delegation in the Saudi capital to offer condolences to King Abdullah after the death of the kingdom's second in line for the throne.
The meetings Thursday come near the end of a three-day mourning period for Crown Prince Sultan, who died last week in New York.
The White House says the Biden delegation also includes CIA Director David Petraeus and Sen. John McCain, the ranking member of the Senate Armed Services Committee.
The process to select a new heir is expected to begin after the VIP visits.
The likely top candidate is the interior minister, Prince Nayef, who is considered among the most conservative members of the royal family.
