SAN FRANCISCO (AP) \u2014 Microsoft is throwing its weight behind Anthropic in asking a federal court to block the Trump administration\u2019s designation of the artificial intelligence company as a supply chain risk.<\/p>\n
Microsoft, in a legal filing, is challenging Defense Secretary Pete Hegseth\u2019s action last week to shut Anthropic out of military work by labeling its AI products as posing a threat to national security.<\/p>\n
The Pentagon took the action against Anthropic after an unusually public dispute over the company\u2019s refusal to allow unrestricted military use of its AI model Claude. President Donald Trump also said he was ordering all federal agencies to stop using Claude.<\/p>\n
\u201cThe use of a supply chain risk designation to address a contract dispute may bring severe economic effects that are not in the public interest,\u201d Microsoft, a major government contractor, said in its Tuesday filing in the San Francisco federal court, where\u00a0Anthropic sued the Trump administration<\/a>\u00a0on Monday.<\/p>\n The Pentagon\u2019s action \u201cforces government contractors to comply with vague and ill-defined directions that have never before been publicly wielded against a U.S. company,\u201d Microsoft\u2019s legal brief says.<\/p>\n It asks for a judge to order a temporary lifting of the designation to allow for more \u201creasoned discussion.\u201d<\/p>\n The Pentagon declined to comment, saying it does not remark on matters in litigation.<\/p>\n
