In an interview with CBS News on Tuesday, Treasury Secretary Janet Yellen said she doesn't see any reason to investigate Musk's use of funds from Saudi Arabia and other countries.
She didn't know what Biden had in mind, but she was aware of concerns that would cause a national security review.
Biden questioned Musk's financing, including the backing of Saudi Prince Alwaleed bin Talal al Saud, but he was not accusing Musk of any wrongdoing.
According to reports, Musk secured $7.1 billion from foreign and US investors to complete his $44 billion purchase of the micro-messaging service.
The purchase should be probed by the Committee on Foreign Investment in the United States on the grounds of national security because of investors with links to China, Saudi Arabia, and other countries.
Last month, the Biden Administration considered a national security review into Musk's business dealings, as the world's richest person seemed to be securing financing from investors in the Middle East. The meeting between Musk and the Kremlin didn't happen. The NSC was unaware of any talks to review Musk's business dealings.
As a result of Musk's purchase, as well as his decision to lay off roughly half of its workforce and his pledge to loosen the social media platform's moderation policies, a wave of advertisers pulled their ads from the site. One of Musk's first initiatives as the platform's CEO was paused after multiple parody accounts took advantage of the feature to buy blue check marks and spread misinformation about celebrities, politicians, athletes and a host of major companies The CEO and CFO of Musk's company have been let go. Last week, as he left the company, the former head of trust and safety warned remaining staff that they will be pressured by management into pushing out changes that will likely lead to major incidents.
The Committee on Foreign Investment in the United States could suspend the acquisition if it decided that the purchase threatens national security.
There is a possible Biden security review of Musk.
There is no basis to investigate Musk's purchase of the social networking site.
