Elon Musk might soon be leaving Washington, but he says DOGE needs to be a long-term project. Musk insisted in a TV interview that the project to slash government spending and eliminate entire agencies ought to endure amid signs that he may soon step away from the effort and return to his struggling electric car company.

Elon Musk suggested his cost-cutting government project DOGE should take a closer look at the Fed’s spending, especially the $2.5 billion it has spent to remodel its Washington D.C. headquarters. Musk’s comments come as he is set to “significantly” cut back his time at DOGE in part to focus on his EV company Tesla.
