Jubeir also distanced Saudi Arabia from Central Intelligence Agency reports that it blamed the Saudi crown prince for Khashoggi's murder.
But shrugging off the scrutiny, the king and crown prince resumed an unprecedented domestic tour Monday with a visit to northern Tabuk region, as they seek to leverage links with different tribes and religious leaders and shore up support for the leadership.
Last week, after offering numerous contradictory explanations for Khashoggi's disappearance, Riyadh said he had been killed and his body dismembered when "negotiations" to convince him to return to Saudi Arabia failed. Germany on Monday announced that it has banned 18 Saudi nationals from entering Europe's border-free Schengen zone due to their suspected connections to the killing. Some U.S. officials, including CIA Director Gina Haspel, have been given access to the recordings, the sources said. Others familiar with the case caution that while it's likely that the crown prince had a role in the death, there continue to be questions about the degree to which he was involved.
The king made the remarks on Monday in his annual policy speech to the kingdom's most senior officials, military officers, clerics and princes.
Saudi-owned Al-Arabiya television reported the prince will attend the upcoming Group of 20 summit in Argentina, his first overseas trip since the murder.
The notion that this crown prince is helping us to stabilize the Middle East, after he ordered the murder of an American citizen - American resident in Turkey, after he launched a blockade against Qatar, after he launched a war in Yemen that the Trump administration, to its credit, is now trying to end, a war that created mass humanitarian suffering, none of these things are in the USA interest.
Earlier on Monday, Yemen's Houthi movement said it was halting drone and missile attacks on Saudi Arabia, the United Arab Emirates and their Yemeni allies, responding to a demand from the United Nations. The U.S. also has sanctioned 17 Saudi officials suspected of being responsible for or complicit in the killing. Paul said the president should cut off arms sales to the kingdom - an action that Trump has repeatedly said he did not want to take. It calls on Yemen's internationally recognized government and the Houthi rebels to agree to a cease-fire around the key port of Hodeida.
Yeni Safak's editor-in-chief, Ibrahim Karagul, wrote in a column on Monday that it was necessary to present "new evidence" regarding the instructions on Khashoggi's murder at Riyadh consulate in Istanbul as well as its organization, preparations and perpetration.
"On Yemen, the administration's recent decision to suspend US aerial refueling for the Saudi coalition absent an actual strategy for ending this conflict is empty action", he said.
Kushner, the president's son-in-law, has worked with the crown prince on various issues, including on how to end the conflict between Israel and the Palestinians.
