The crown prince's links to the Khashoggi murder have always been known to most Western intelligence agencies, they just weren't made public. It did not mention the Khashoggi report, a test of the decades-long close ties between the allies as they try working together to confront growing Iranian influence in the Middle East.
Riyadh has denied any involvement by the crown prince, Saudi Arabia's de facto ruler.
Biden pledged as a candidate to make Saudi Arabia "a pariah" over the killing. They fear Biden will go with condemnation instead, eschewing a lasting standoff with the likely future ruler of an important, but often hard, USA strategic ally, valued both for its oil reserves and its status as a counterbalance to Iran in the Middle East.
"For the sake of accountability and for the sake of American democracy, the DNI report must be released", Callamard said. "So it's a day of reckoning, but one that's long overdue".
Twenty-one men were arrested in the killing and five senior officials were fired, including the deputy intelligence chief, Ahmad Asiri, and Saud al-Qahtani, a senior aide to the crown prince.
Critics blame Mohammed bin Salman for the kingdom's imprisonment and alleged torture of peaceful rights advocates, businesspeople and other royals at home and for launching a devastating war in neighbouring Yemen and a failed economic blockade against neighbouring Qatar, among other actions.
Given his age and Saudi royals' longevity, the prince could rule for the next half-century, if he follows his aging father to the throne.
The Saudi Arabia Embassy spokesman in Washington did not immediately respond to a request for comment Thursday.
Saudi officials have said Khashoggi's killing was the work of rogue Saudi security and intelligence officials. He planned to pick up documents for their wedding.
People take part in a vigil to remember Khashoggi outside the Saudi Consulate in Istanbul on October 25, 2018.
Turkey's secret recordings from inside the Saudi Consulate - itself a diplomatic misdemeanour that has been largely overlooked amid the horror of Khashoggi's murder - have also been shared with other Western intelligence agencies. The whereabouts of his remains remain unknown.
The report was released in a manner choreographed to limit damage to U.S. -Saudi ties.
Earlier this month, the Biden administration had imposed a temporary freeze on billions of dollars in weapons sales to two countries, including the sale of precision-guided munitions to Saudi Arabia and F-35 fighters to the UAE, according to The Wall Street Journal.
The statement, which also did not mention the Khashoggi report, said the leaders reviewed "destabilizing" Iranian regional activities, the US "commitment to defend" Saudi Arabia "against such threats" and an assurance from Biden not to allow Iran "to possess nuclear weapons". He's given few details of what weapons and support he meant.
The White House said Biden was sending a signal by insisting that he would deal only with the king, in leader-to-leader conversations.
"There are also areas where we will continue to work with Saudi Arabia given the threats they face in the region", she added in an apparent reference to Saudi Arabia's main rival and USA foe, Iran.
A classified version of the report was presented to Congress in late 2018, but the Trump administration rejected demands by lawmakers and human-rights groups to release a declassified version. The Biden administration agreed to release a declassified version.
Five people were convicted of the murder and given the death penalty in a 2019 trial, but their sentences were commuted to 20 years in jail after Khashoggi's family forgave them. They were not identified.
