Microsoft and retired military leaders are backing Anthropic in its legal battle against the Trump administration's classification of the company as a 'supply chain risk.' This designation could severely impact Anthropic's ability to secure government contracts and has raised concerns about the implications for AI technology in military applications.

Microsoft supports Anthropic's stance against mass surveillance and autonomous weapons use.
