Elon Musk’s $44 billion deal to acquire Twitter hasn’t escaped government scrutiny just yet. According to a report from Bloomberg, the US government is looking into whether Musk’s foreign investment partners have access to users’ private data on the platform.

Sources close to the situation told Bloomberg that the government’s asking for more details about Musk’s private agreements with the international investors who hold stakes in the company, which include Saudi Arabia’s Prince Al Waleed bin Talal Al Saud and the Qatar Investment Authority. Musk’s business dealings in both Ukraine and China have also drawn concern.

Separately, a number of lawmakers, including Richard Blumenthal (D-CT), Dianne Feinstein (D-CA), Elizabeth Warren (D-MA), Ed Markey (D-MA), Ben Ray Luján (D-NM), and Cory Booker (D-NJ), are also pushing for the Federal Trade Commission to take action against Twitter.

Twitter is also on the hook to comply with the conditions of the settlement it reached with the FTC earlier this year over claims it used personal information to sell targeted ads. As reported by The Verge’s Alex Heath, Twitter’s lawyer has already warned the company could face billions in fines if it doesn’t follow the agency’s consent order.
