A disturbing image of Senator Mitch McConnell appearing to lie in a hospital bed, covered in tubes and in extreme distress, spread rapidly across X and Reddit earlier this week. It looked alarming. It also wasn’t real.
Google’s SynthID system, developed by its DeepMind AI lab, identified the image as AI-generated on July 8, 2026. The watermarking technology detected invisible markers embedded in the synthetic content, confirming what fact-checkers at Snopes and Lead Stories had also concluded: the photo was fabricated, likely using OpenAI’s image generation tools.
How SynthID actually works
When an AI model creates an image, SynthID embeds an imperceptible digital watermark directly into the pixels. Humans can’t see it. Machines can read it instantly.
Google first deployed SynthID through its DeepMind division, and in May 2026, OpenAI integrated the same watermarking standard into its own image generation tools. That cross-platform adoption turned out to be crucial here, because it meant the McConnell image carried detectable markers regardless of which platform it surfaced on.
