What is Elon Musk's actual role at Doge and why is this revelation legally significant?

According to Barbara McQuade, contrary to what many assumed, Elon Musk is not the head of Doge but merely a Senior Adviser to President Trump without any official authority. This revelation came during a lawsuit against Musk and Doge, and it contradicts the impression given at a previous Oval Office press conference where Trump asked Musk to speak about his work with Doge. This clarification is legally significant as it may influence ongoing lawsuits, potentially giving Judge Chutkan a new perspective on the case or opening the door to different legal approaches. The distinction between being in charge versus serving as an adviser could have important implications for Musk's legal liability and influence over federal agencies.
