On Thursday, House Judiciary Chair Jim Jordan (R-OH) sent letters to 16 American technology firms, including Google and OpenAI, asking for past communications with theBiden Administration that might suggest the former President coerced or colluded with companies to censor lawful speech in AI products.The Trump Administrations top technology advisers previously signaled it would pick a fight with Big Tech over AI censorship, which is seemingly the next phase in the culture war between conservatives and Silicon Valley. Jordan previously led an investigation into whether the Biden Administration and Big Tech colluded to silence conservative voices on social media platforms. Now, hes turning his attention to AI companies and their intermediaries.In letters to technology executives including Google CEO Sundar Pichai, OpenAI CEO Sam Altman, and Apple CEO Tim Cook, Jordan pointed to a report his committee published in December that he claims uncovered the Biden-Harris Administrations efforts to control AI to suppress speech.In this latest inquiry, Jordan asked Adobe, Alphabet, Amazon, Anthropic, Apple, Cohere, IBM, Inflection, Meta, Microsoft, Nvidia, OpenAI,Palantir, Salesforce, Scale AI, andStability AI for information. They have until March 27 to provide it.TechCrunch reached out to the companies for comment. Most didnt immediately respond. Nvidia, Microsoft, and Stability AI declined to comment.Theres one notable omission in Jordans list: billionaire Elon Musks frontier AI lab, xAI. That may be because Musk, a close Trump ally, is a tech leader whos been at the forefront of conversations about AI censorship. The writing was on the wall that conservative lawmakers would ramp up scrutiny over alleged AI censorship. Perhaps in anticipation of an investigation such as Jordans, several tech companies have changed the ways their AI chatbots handle politically sensitive queries.Earlier this year, OpenAI announced it was changing the way it trains AI models to represent more perspectives and ensure ChatGPT wasnt censoring certain viewpoints. OpenAI denies this was an attempt to appease the Trump administration, but rather, an effort to double down on the companys core values.Anthropic, for its part, has said that its newest AI model, Claude 3.7 Sonnet, will refuse to answer fewer questions and give more nuanced responses on controversial subjects.Other companies have been slower to change how their AI models treat political subject matter. Leading up to the 2024 U.S. election, Google said that its Gemini chatbot wouldnt respond to political queries. Even well after the election, TechCrunch found that the chatbot wouldnt consistently answer even simple questions related to politics, like Who is the current President?Some tech execs, including Meta CEO Mark Zuckerberg, have added fuel to conservative accusations of Silicon Valley censorship by claiming the Biden Administration pressured them to suppress certain content like COVID-19 misinformation.
