Earlier on Sunday, the Saudi stock market plunged almost seven percent amid fears of imminent sanctions by the U.S. after President Donald Trump threatened a severe punishment if the kingdom was found responsible for the journalist's disappearance.
He said Riyadh would "respond to any action with a bigger one", pointing out that the oil superpower "plays an effective and vital role in the world economy".
After Saudi journalist Jamal Khashoggi disappeared, Turkish officials said privately that they knew exactly what happened to him: he'd been murdered at the Saudi consulate in Istanbul, dismembered and his body moved out in boxes. Those plans could change as details of the investigation become available, Kudlow said. The index recovered some ground later to close 3.5% down.
Khashoggi, a Washington Post columnist and permanent United States resident, had fallen out of favor after previously enjoying close ties with the Saudi royal family.
John Brennan, the former Central Intelligence Agency director who previously served as a Central Intelligence Agency station chief in Saudi Arabia, said Sunday during an appearance on "Meet the Press" that Crown Prince Mohammed bin Salman has become "emboldened" to be more aggressive by his relationship with Trump and Jared Kushner, the president's son-in-law and a top White House aide. But Trump has said he does not want to halt a proposed $110 billion arms sale to Saudi Arabia because, he maintained, it would harm US manufacturers. US President Donald Trump threatened on Saturday to "punish" Riyadh if it were proven to be behind the suspected killing.
Trump has not described what punishment Saudi Arabia might face.
In a joint statement, the nations called for a "complete and detailed response" from Saudi Arabia.
Saudi Crown Prince Mohammed bin Salman has aggressively pitched the kingdom as a destination for foreign investment.
Saudi Arabian equities slumped on concern the nation's relationship with the US may sour over the disappearance of Washington Post columnist Jamal Khashoggi. But Khashoggi's disappearance, and suspicions he may have been targeted over his criticism of the crown prince, have led several business leaders and media outlets to back out of an upcoming high-profile investment conference in Riyadh.
The Saudis have said the allegation is "baseless", but have provided no proof that Khashoggi left the diplomatic outpost alive after arriving to pick up documents for his impending marriage.
"I think one of the strong things that we can do is not only stop military sales, not only put sanctions on Saudi Arabia, but most importantly, get out of this awful, bad war in Yemen led by the Saudis", Sanders said on CNN's "State of the Union".
"So, we do that, we really are hurting our country a lot more than we're hurting Saudi Arabia".
He expressed the UAE's total rejection of all attempts that would harm Saudi Arabia's fundamental role in establishing regional security and peace and the kingdom's Arab, Islamic and global reputation.
According to Rubio, the USA rightly condemns corrupt leaders like Vladimir Putin in Russia, Bashar Assad in Syria and Nicolás Maduro in Venezuela and should absolutely condemn the Saudi regime if the allegation is proven true - regardless of whether we are foes or allies.
