US President Donald Trump has signed an executive order aimed at unifying AI regulation across the country. The order, which was signed on Thursday evening, directs federal agencies to take measures to reduce or eliminate the impact of state laws on AI regulation. The order specifically targets Colorado's recent consumer protection law, which prohibits 'algorithmic discrimination' and may force AI models to produce false results. The order also establishes an 'AI Litigation Working Group' led by the Attorney General to sue states whose laws do not align with the goal of maintaining and enhancing the US's global AI leadership position. This move has been seen as a victory for the tech industry, but has raised opposition from some Republican state governors. The executive order is part of the US's overall strategy to compete with China in the AI domain.
