Elon Musk, the tech billionaire and world’s richest man, has officially taken on a role as a special government employee under former President Donald Trump. The White House shared the news, confirming that Musk now serves in this unique capacity.

While Musk isn’t a full-time federal employee, he’s not just a volunteer either. This designation means he’s expected to work for the government for up to 130 days within a year. Interestingly, he’s not receiving any payment for this role, according to sources close to the matter.

Musk has already been granted top-secret security clearance and has an office on the White House grounds. His influence within the Trump administration has been growing, with the former president recently confirming Musk’s access to the Treasury Department’s payment system—a critical component of federal financial operations.

However, this move hasn’t been without controversy. Federal unions and other groups have sued the Treasury Department over Musk’s access, raising concerns about potential conflicts of interest. Trump has assured that Musk’s actions will require White House approval, saying, “Where not appropriate, we won’t [give approval].”

As a special government employee, Musk is subject to federal ethics laws, which prohibit involvement in matters that could affect his financial interests. Yet, experts have expressed skepticism about whether the Trump-era Justice Department would enforce these regulations against a close ally like Musk.

It remains unclear whether Musk will be required to file a public financial disclosure. This will depend on his salary level and duration of service. Meanwhile, Musk’s ties to Trump’s policies are already impacting his businesses. For instance, Ontario recently canceled a contract with Musk’s Starlink satellite internet service following Trump’s announcement of tariffs on Canada.

As Musk’s role continues to evolve, the public will be watching closely to see how this billionaire entrepreneur navigates his dual responsibilities in government and business.
