White House press secretary Karine Jean-Pierre explained the Biden administration's decision to request immunity for Saudi Arabia's Crown Prince, Mohammed bin Salman in lawsuits over his alleged role in the killing of Washington Post journalist Jamal Khashoggi in 2018.

"So, look, again, this is immunity. Determination is a legal one. That's what I was laying out earlier. The United States consistently has afforded head of state immunity to heads of government, such as prime ministers consistent with customary institutional law," Jean-Pierre said. "U.S. practice on this issue is longstanding and consistent, including a number of head of state immunity cases from the past four administrations."

Her comments come after the State Department made the determination on Thursday that Prince Mohammed, also referred to as MBS, should be immune from lawsuits over his alleged role in the death of Khashoggi.

The State Department called the decision "purely a legal determination," citing longstanding precedent on the issue.

In the filing, the State Department said that it "takes no view on the merits of the present suit and reiterates its unequivocal condemnation of the heinous murder of Jamal Khashoggi."

When President Biden was running for his current office in 2019, he said that he planned to make a "pariah" of Saudi leaders over Khashoggi's death. He made the comments during a Democratic primary debate in 2019.

"And I think we should have nailed it as that. I publicly said at the time we should treat it that way and there should be consequences relating to how we deal with those — that power," Biden said.
