Ahead of the deadline, a group of Republican and Democratic senators on Thursday renewed their push to penalize Saudi Arabia, unveiling legislation to bar some arms sales and impose sanctions on those responsible for Khashoggi's death.
The official said in an emailed statement that Trump maintains his discretion to decline to act on congressional committee requests when he feels it's appropriate.
The crown prince is the next in line to the Saudi throne behind his ailing father King Salman, and has become the de facto ruler of Saudi Arabia.
Khashoggi was last seen alive entering the Saudi consulate in Istanbul on 2 October.
The leaks are said to have come from United States intelligence agencies that are "working through" piles of intercepts.
Saudi Arabia quietly held a second court hearing for 11 people facing charges over the killing of journalist Jamal Khashoggi, an independent United Nations human rights expert said, criticising the kingdom for its lack of transparency in the proceedings over the grisly slaying. His remains have not been found.
But Saudi officials insist he was murdered by a "rogue" team of Saudi agents not acting on the prince's orders.More news: Frank Robinson, MLB's first black manager, dies at 83

"I can't comment on reports based on anonymous sources", al-Jubeir said.
The U.S. Senate issued a resolution condemning Saudi Arabia's Crown Prince Mohammed bin Salman for Khashoggi's murder in December, following a Central Intelligence Agency report concluding his responsibility.
Turkey has sought the extradition of the Saudi suspects, but the kingdom has rejected any notion they could be tried overseas and has not allowed Turkey access to them.
Callamard, who was on a trip in Turkey, said that Saudi Arabia also hampered Turkey's efforts to investigate the case at the consulate.
Congressional leaders triggered the Magnitsky Act in October, giving the administration 120 days, until February 8, to report back on who was responsible for the death of Khashoggi, a US resident killed at the Saudi consulate in Istanbul, Turkey, and whether it would impose sanctions on that person or persons. It's unclear if they remain detained during the trial or where they're being held.
The official said the White House would continue to consult with Congress on the murder of Khashoggi, a Washington Post columnist.
Saudi Arabia has repeatedly denied Salman's involvement in the murder, and in December condemned a US Senate resolution accusing him of ordering the killing of the journalist.
