Boris Johnson's Brexit proposals dismissed as 'fantasy world' by Chancellor
The profiles of former foreign secretary Mr Johnson and Environment Secretary Michael Gove were among those reportedly accessed. The uncertainty has led to business concerns that there will be no deal, potentially leading to tariffs and border delays.
While this is not the first time that Musk tweeted a music video whose lyrics are clearly not related to his business dealings, avid Twitter followers of the Tesla CEO speculated that Monday's cryptic message was a veiled reference to "operating profit positive".
In addition to Tesla, Musk is also CEO of SpaceX, The Boring Company, and Neuralink. A former SEC enforcement lawyer told Bloomberg the SEC "can theoretically seek to pull the settlement" if they feel Musk isn't complying with the agreed-upon settlement, which included orders for Tesla to implement controls over Musk's communications.

The tweet calling the SEC the "Shortseller Enrichment Commission" came just hours after a federal judge ordered Musk and the SEC to write a letter justifying a settlement which allows him to remain in charge at Tesla.
The SEC declined to comment Thursday. The settlement was announced on September 29, two days after Musk was charged.
