Billionaire investor Mark Cuban cautioned Tesla CEO Elon Musk against aligning with Donald Trump. According to Cuban, Trump’s loyalty is only to himself. Cuban’s comments came in response to Musk amplifying conspiracy theories about Democrats and immigration. Cuban suggested Musk could later regret supporting Trump, as previous allies have been left without reciprocation. Mark Cuban has expressed interest in a role at the Securities and Exchange Commission, aiming to bring changes to the agency. Elon Musk has proposed leading a government efficiency commission to reduce federal spending if Trump wins a second term, which Trump endorsed.
