How AI Chatbots Are Amplifying Partisan “Pink Slime” Local News — And Why It Matters for the 2026 Midterms

AI chatbots are increasingly shaping how voters learn about candidates — and a new NewsGuard audit suggests many of those summaries rely on partisan outlets posing as independent local news. These so-called "pink slime" sites publish politically motivated coverage without clear disclosure, and chatbots frequently cite them as authoritative sources.

Key Findings From the Audit

NewsGuard tested seven major consumer-facing chatbots using prompts tied to recent coverage from 12 pink slime sites across six battleground states (Ohio, Georgia, North Carolina, Alaska, New Hampshire and Iowa). The audit found:

• Pink slime sites appeared in 48.2% of chatbot responses to election-related prompts, and were the only cited source in 7.7% of responses.
• Platform citation rates varied widely: ChatGPT 70.8%, Copilot 54.2%, Perplexity 54.2%, Claude 50%, Gemini 41.7%, Meta AI 37.5%, Grok 29.2%.
• Chatbots cited left-leaning pink slime sites in 36.3% of responses versus right-leaning sites in 11.9% — a gap NewsGuard says may reflect higher publishing volume by the left-leaning networks rather than an intrinsic AI political bias.
• Of 168 chatbot answers examined, only one explicitly noted that a cited source was partisan.
• NewsGuard reported that, as of September 2026, it had identified 1,179 pink slime sites in the U.S., compared with 937 remaining daily newspapers.

Who Runs These Sites?

The audit focused on sites tied to three networks: the left-leaning American Independent Network and Courier Newsroom, and the right-leaning One Nation network (aligned with the Senate Leadership Fund PAC). Many of these outlets use innocuous local names (for example, "Ohio Independent," "Peach State Post," "Iowa Starting Line") while obscuring ownership and funders.

Examples From the Audit

When asked whether Alaskan Sen. Dan Sullivan voted against lifting tariffs that affect the fishing industry, all seven chatbots cited AlaskaIndependentNews.com, a site in the American Independent Network. In questions about Georgia Sen. Jon Ossoff and tax votes, multiple chatbots cited PeachStatePost.com, which is associated with One Nation.

In another test, only xAI's Grok labeled a cited source (GranitePostNews.com) as "partisan" — an exception in the sample of 168 responses.

How These Sites Reach Chatbots

Pink slime outlets amplify reach through two main channels: publishing frequent content that is crawled by search engines and spending on social-media ads to drive traffic. The audit cites advertising totals in 2026: the American Independent Media network spent roughly $342,700–$429,850 on Facebook and Instagram promotions (at least 38.9 million views), while One Nation's network spent approximately $450,000–$596,000 (at least 58.6 million views).

Why This Matters

Chatbots often present answers in a flat, authoritative tone that can obscure the partisan origin of a source. That "laundering" effect can make one-sided or spin-driven coverage appear neutral to voters who consult chatbots for quick summaries or fact checks in the run-up to closely contested midterm races.

"The more diverse this information comes, the more that this affects the amplification... Not only does it affect amplification, it affects future AI." — John Mark Dougan, quoted at a 2025 conference on disinformation

Context and Caveats

NewsGuard emphasizes that higher citation rates for left-leaning networks may be driven largely by their higher volume of published stories during the audit period. Chatbots draw on large swaths of public web content and typically do not filter by editorial standards the way specialized, professionally curated tools do.

Microsoft told NewsGuard that Copilot is "designed to ground answers in high-quality search results" and encourages users to review sources. Other companies audited did not provide comment.

What Readers Should Do

• Check the original source: follow the chatbot's citations to the underlying story and confirm disclosures about ownership or funding.
• Cross-check coverage with independent local news outlets and multiple reputable sources before drawing conclusions.
• Be cautious of single-source summaries, especially when a chatbot cites only one article for a contested political claim.

As AI becomes a larger part of how people access news, understanding how partisan networks can shape the information ecosystem is essential — especially during high-stakes elections.
