STORY: U.S. President Joe Biden arrived in Jeddah, Saudi Arabia, hoping to tackle a host of issues from global oil production to confronting Iran - but almost immediately drew criticism for this moment: a fist-bump with the Saudi Crown Prince, Mohammed bin Salman.

U.S. intelligence believes the prince, also known as MbS, ordered the murder of the American-based Washington Post journalist Jamal Khashoggi in 2018. MbS denies involvement.
