US intervenes to protect state secrets in Saudi Crown Prince's vendetta against former spy

If the court case is allowed to proceed, the Justice Department said in a motion filed Tuesday, it could lead to "the disclosure of information that could reasonably be expected to damage the national security of the United States." The case was brought against Saad Aljabri, a former top Saudi counterterrorism official who is widely respected by US intelligence and counterterrorism officials and credited by them with saving hundreds, maybe thousands, of American lives. Aljabri -- who fled to Canada in 2017 -- became a nemesis of the Crown Prince, Mohammed bin Salman, after working for years alongside the country's head of counterterrorism, Prince Mohammed bin Nayef, who was a rival of Salman's for the throne. A group of Saudi companies owned by the Kingdom's sovereign wealth fund, which the prince controls , then brought embezzlement cases against Aljabri, first in Canada and now the United States. Aljabri denies the accusations and accuses the prince, known as MBS, of sending an assassination squad to Canada to try to kill him and of holding two of his children hostage in Saudi Arabia. Saudi Crown Prince accused of assassination plot against senior exiled official Aljabri has alleged that MBS made multiple attempts to lure him back to Saudi Arabia and said that the hit team sent to Canada was part of the same team that had killed journalist Jamal Khashoggi just days earlier. The group of Saudi companies that has brought the cases against Aljabri was, according to the Justice Department's own filing, established "for the purpose of performing anti-terrorism activities." The holding company, called Sakab, accuses Aljabri of defrauding them. In order to defend himself against the charges, the Justice Department says Aljabri intends "to describe and present evidence regarding alleged sensitive national security information." "It's definitely rare for such [Justice Department] filings to occur," said Marc Raimondi, who recently left the Justice Department where he served as a spokesman for the National Security Division. According to a source who used to serve in government and is familiar with the case and intelligence, the classified information that could come to light includes intelligence relationships, operations, classified sources and methods. The revelations could also be embarrassing, particularly to Obama-era officials, given the often "unseemly" nature of the intelligence world, the source added. 'The right thing to do' "It's the right thing to do. You don't want to disclose these things," the source said. By bringing the case against Aljabri in the United States, Saudi Arabia and its defacto ruler have put not only the US in a difficult position but prioritized the feud with Aljabri over the two countries' relationship , the former government source said. The source added: "It appears to me a very personal vendetta that doesn't have long term interests both for the kingdom and for the US and for intelligence cooperation in the future." The Saudi embassy in Washington did not immediately respond to CNN's request for comment. Last week, a bipartisan group of senators wrote to President Joe Biden praising Aljabri's two decades of partnership with the US and calling on Biden to help with Aljabri's imprisoned children, Omar and Sarah, 22 and 21, respectively. They also highlighted the danger MBS's campaign against Aljabri presents to US national security and directly reference the possibility that classified information could be exposed. 'Using the children as leverage' "The Saudi government is believed to be using the children as leverage to blackmail their father and force his return to the kingdom from Canada, where he currently resides in fear of possible retribution for his previous support for a rival of Saudi Crown Prince, Mohammad Bin Salmon [sic]," the letter reads, which was signed by Sens. Marco Rubio, Tim Kaine, Patrick Leahy and Ben Cardin.
