A group of seven Republican U.S. senators has formally requested the Commerce Department to assess potential data security vulnerabilities associated with Chinese open-source artificial intelligence models, specifically highlighting DeepSeek. The senators' letter calls for a thorough evaluation of the national security risks posed by these AI technologies. Concurrently, Democratic lawmakers, including Senator Elizabeth Warren, have raised concerns about Google's recent settlement with the Trump administration related to censorship lawsuits, sending a letter to Google and YouTube CEOs questioning the terms and potential quid-pro-quo arrangements.
