The US Securities and Exchange Commission (SEC) is moving to impose sanctions against Elon Musk following his failure to appear for testimony in an investigation related to his $44 billion acquisition of Twitter. The regulator criticized Musk for prioritizing attendance at a rocket launch over his deposition, prompting discussions of a potential contempt ruling. The SEC's actions come amidst concerns about Musk's compliance in the scrutiny of his business dealings, suggesting that the agency views this as more than just an oversight, but as a significant violation that warrants strong disciplinary measures.
