What could potentially check or limit Elon Musk's growing power in Washington?

According to Teddy Schleifer, the courts appear to be the primary guardrail that could stop or limit Elon Musk's expanding influence in Washington. While Musk seems to be successfully challenging bureaucracy with his numerous initiatives, the judicial system remains one of the only effective checks on his power. Congress appears compliant and willing to go along with whatever Trump does, and Trump similarly seems amenable to Musk's suggestions. This creates a situation where traditional legislative oversight is weakened, leaving the courts as the last meaningful constraint on Musk's activities.
