Tesla's chief executive Elon Musk's told investors Monday in a blog post that he was confident the funding required to take the electric automaker private was secured by Saudi Arabia, but required support from federal regulators of that foreign funding could be another hurdle for this strange saga.

Any move by Tesla to take the company private using overseas funds would likely have to receive support from the Committee of Foreign Investment in the United States (i.e., CFIUS), the inter-agency committee tasked with reviewing the national security implications of foreign investments in U.S. companies.
