What is Elon Musk's actual role in the Trump administration according to the clip?

According to the clip, Elon Musk is officially described as 'a senior adviser to the President, not the administrator of that advisory group.' However, Ari Melber suggests there's a discrepancy between this official description and reality. He points out that Trump's lawyers are attempting to downplay Musk's influence by claiming 'that Musk's role is very small, that he's not doing what he's actually doing.' This indicates potential confusion or deliberate mischaracterization of Musk's actual level of involvement and influence within the administration, with his true role potentially being more significant than publicly acknowledged.
