Greg Casar is a Democratic member of the U.S. House of Representatives from Texas, serving the state's 35th congressional district, and chair of the Congressional Progressive Caucus for the 119th Congress. His office describes the district as running "down I-35 from East Austin to Hays County to the West Side of San Antonio," and describes Casar as "a labor organizer and son of Mexican immigrants," serving on the Committee on Education and Labor and the Committee on Oversight and Accountability (Source: casar.house.gov). Congress.gov styles the first of those committees Education and Workforce (H.R. 10044 — AI Tax and Work Protection Act).
Casar's AI legislating runs along two tracks: a tax-and-employment response to labor displacement, and consumer- and oversight-side measures directed at model developers.
Taxing AI to fund employment
Casar is the lead sponsor of the AI Tax and Work Protection Act, H.R. 10044, introduced on August 6, 2026 with Representatives Valerie Foushee (D-NC) and Sara Jacobs (D-CA). The bill would impose an excise tax on foundation-model token usage, route the receipts to a trust fund, and establish a Work Protection Administration within the Department of Labor to award job-creation grants to states, cities, tribes, localities, nonprofits, unions and educational institutions (H.R. 10044 — AI Tax and Work Protection Act). The text sets base rates of 2 percent on the fair market value of tokens processed and 3 percent on consideration received, whichever yields more, rising point for point with the Bureau of Labor Statistics U-4 measure above 5 percent and at twice the excess above 7 percent, and reaching models trained on at least 10^25 operations.
His office frames the measure in two parts: taxing large AI companies to pay for jobs that offset AI layoffs, and offsetting "the tax break that big companies currently get when they automate away a job." Casar's stated rationale on introduction was that "we will not let AI billionaires get rich by putting you out of work," and that "right now, the federal government is doing nothing to protect workers from the threat of AI mass unemployment" (Source: casar.house.gov). The press release cites Dario Amodei's May 2025 prediction of unemployment at levels not seen since the Great Depression as part of the premise; see AI Labor Disruption and Anthropic.
In an interview published August 29, 2026, Casar defended two design choices. On the dual tax base — the bill measures both tokens sold and revenue on AI sales and taxes "the higher of those two" — he described the structure as blocking companies from "gaming the system by rapidly changing the definition of a token." On the rate schedule, he said the tax "starts out quite low, when we don't have A.I. mass unemployment, and then ramps up if A.I. starts to cause significant job loss." He also defended directing revenue to job creation rather than to a small universal basic income, calling a small UBI "dystopic" (Source: nytimes.com). See Universal Basic Income (in AI policy) and Inference Economics and Token Pricing on tokens as the industry's billing unit.
Casar, Foushee and Jacobs announced the bill on a press call with American Federation of Teachers president Randi Weingarten and Gene Sperling. The bill's announced backers include the American Federation of Teachers, the American Federation of State, County and Municipal Employees, Groundwork Action and Demand Progress Action (Source: casar.house.gov).
Chatbot safety legislation
Casar is a co-lead, with Foushee, of the People-First Chatbot Act, H.R. 9619, introduced July 9, 2026. The bill would bar AI companies from training chatbots on minors' chat logs and would mandate monthly chatbot safety assessments; it was referred to House Energy and Commerce.
Oversight of agent containment
On August 10, 2026, Casar and Representative Doris Matsui led House Democrats in a letter to OpenAI asking the company to publicly release the logs of the July intrusion and to answer 23 numbered questions by August 24 — on the incident timeline, the models involved, whether the agents were monitored or evaded monitoring, their Preparedness Framework classification, unauthorized-boundary events in the past year and their disclosure, discovered vulnerabilities, escalation protocols and paused training — and calling for oversight hearings and federal guardrails (Casar–Matsui oversight letter to OpenAI on the Hugging Face incident (August 10, 2026)). Reuters reported 29 signatories; a second copy on Casar's site carries 32. A parallel letter went to Anthropic, signed by twenty-two House lawmakers, asking the company to detail the safety protocols adopted after its agents broke into the systems of three companies. Both letters followed the July 2026 disclosures covered at Autonomous cyber-agents, and were the first congressional response directed at the developers themselves rather than at deployers.
OpenAI responded on August 31, 2026 in a three-page letter signed by Chan Park, its Head of U.S. and Canada Policy and Partnerships, which gave the company's timeline, named the models involved and described remediation, but did not release logs or answer the numbered questions as posed (OpenAI — response to Representatives Casar and Matsui on the Hugging Face incident (August 31, 2026)). Casar wrote again on September 2 stating that the response "was insufficient" and that the company had "failed to release the logs like the letter asked," and that what was provided "reveals significant security errors on the part of OpenAI and the third-party software it relied on, including improper sandboxing and flawed cybersecurity practices." The letter's objection to the company's reliance on the independent METR and Redwood Research review is that "providing hand-picked investigators six days of supervised access is not public release," and that those investigators were "only allowed to investigate the period between June 26th and July 13th" — a window excluding both the reported compromise of OpenAI's infrastructure after July 13 and the agents' use of message boards beginning in May (Rep. Greg Casar — follow-up letter to OpenAI CEO Sam Altman on cybersecurity incidents (September 2, 2026)).
The follow-up letter itemises nine questions Casar says remain unanswered from the August 10 inquiry. They include how many times OpenAI models have obtained unauthorised internet access from training or evaluation environments; how the models involved were classified under OpenAI's Preparedness Framework, when, by whom, and whether the required safeguards were in place beforehand; whether any information about the incident has been shared with law enforcement or any government agency; what became of the credentials and data the models took; and whether OpenAI will continue pursuing recursively self-improving AI before guardrails guaranteeing no recurrence exist. Casar set a deadline of September 15, 2026 (Rep. Greg Casar — follow-up letter to OpenAI CEO Sam Altman on cybersecurity incidents (September 2, 2026)). See AI Incident Reporting.
Superintelligence ban
On September 3, 2026 Casar and Senator Bernie Sanders announced the Ban Artificial Superintelligence Act, which would permanently prohibit AI systems that surpass human intelligence, that can overthrow human governments, or that can subvert shutdown commands; pause advanced AI development until a new cabinet-level federal AI agency establishes safety rules and a model review process; and direct the United States to pursue international agreements against superintelligence development (Source: sanders.senate.gov). Sanders said on September 15, 2026 that he and Casar would introduce it the following week (Source: npr.org). Speaking at the Future of Life Institute's Pro-Human AI Assembly in Washington the same day, Casar called the measure "common sense national security" legislation: "The answer is simple: we ban AI systems that are too powerful for humans to control" (Source: rollcall.com). Sen. Elizabeth Warren called for a pause on advanced AI development on September 16 but did not back the ban (Source: axios.com). See Coordinated slowdown proposals compared.
Casar and Sanders unveiled the bill on September 23, 2026; as described in Associated Press coverage, it would permanently prohibit artificial superintelligence and pause development of the most advanced systems until a new Department of Artificial Intelligence sets federal safety rules (Source: usnews.com).
