A new study by AllSides has found that major news aggregators, including Google News and Microsoft’s Bing News, continue to feature a disproportionate number of articles from left-leaning outlets in their non-personalized sections.

The analysis determined that Google News drew just 1% of its articles from right-leaning outlets and 73% from left-leaning ones during the sampled periods in late 2025. Similar imbalances appeared on other platforms, the New York Post reported.

White House Press Secretary Karoline Leavitt highlighted the findings on X, writing: “It’s not just Apple News — left-wing bias rampant on Google News, Yahoo and Bing: bombshell study.” She linked to coverage in the New York Post.

AllSides, which rates media bias using a multi-partisan panel, blind surveys, and expert reviews, audited the human-curated “Top Stories” and “U.S. News” sections of the aggregators. The group assigned bias ratios, with more negative scores indicating a stronger leftward tilt.

Google News received a rating of -1.62, the most skewed among those reviewed.

Apple News showed 2% of articles from right-leaning outlets and 50% from left-leaning ones, for a bias ratio of -1.57. Bing News featured 5% right-leaning and 72% left-leaning content, with a ratio of -1.55. Yahoo News posted 2% right-leaning and 53% left-leaning, also at -1.55. The audits examined between 140 and 315 articles per platform.

Julie Mastrine, director of AllSides’ media bias rating system, stated that by failing to provide balanced feeds, the aggregators are “prevent[ing] Americans from considering multiple views and thinking independently.” She added, “The impact of one-sided media on our society is both sinister and immeasurable, as these aggregators enjoy massive reach, in the tens of millions of users,” per The Post.

The latest AllSides data builds on prior reviews of Apple News and aligns with earlier findings from the Media Research Center. In March 2026, Leavitt shared a Media Research Center analysis on X that found Google News featured just 2% of top morning stories from conservative outlets.

 

Mark Grabowski, communications department chair at Adelphi University, described the AllSides data as “damning” for companies that have long claimed neutrality. Dan Schneider of the Media Research Center warned that reliance on these platforms, which supply news to roughly half of Americans, risks exposing users to skewed narratives without their knowledge.

Google disputed the conclusions. A spokesperson told the New York Post the study relied on “arbitrary ratings and a tiny two-week snapshot” while overlooking how personalization and user interests shape results. Apple has maintained that its trending sections draw from readership data rather than pure editorial choice. Yahoo said it works with hundreds of outlets across the ideological spectrum.

Other aggregators showed less imbalance. SmartNews and NewsBreak moved into the Center category in the updated ratings. RealClearPolitics rated Center at 0.17, and AllSides itself at 0.09. White House Wire, launched by President Donald Trump in May 2025 as an alternative aggregator, received a Lean Right rating of 2.50. The Drudge Report scored Lean Left on content but shifted further left when accounting for headlines.

The findings arrive amid ongoing scrutiny of tech platforms by federal regulators and the Trump administration.
