Elon Musk's $44 billion purchase of Twitter could face a probe into potential national security risks posed by Musk's foreign investors, according to a Reuters report on Friday. The foreign investment could invite "the kind of regulatory scrutiny over US national security that social media peer TikTok faced," the report said.

Musk's investors include Qatar's sovereign wealth fund and Saudi Arabia's Prince Al Waleed bin Talal al Saud. The Saudi Kingdom Holding Company already owns 5.2 percent of Twitter stock and plans to roll that $1.9 billion stake into Musk's privatized Twitter. The Qatar investment is for $375 million.
