What is Elon Musk's actual role in the Department of Government Efficiency (DOGE) and how does it differ from previous statements?

According to a recent court filing, Elon Musk is serving as a senior adviser rather than an administrator within DOGE, contradicting previous White House statements. While Musk previously conveyed himself as personally responsible for federal layoffs, the White House now clarifies that agency heads, not Musk, are making the final decisions regarding federal employment. This clarification comes amid legal challenges from over 18 state attorneys general questioning the constitutionality of Musk's involvement in government operations and his influence over federal employee terminations.
