Overview

• TF1’s Les Vérificateurs determined the MSNBC clip showing crowds in Boston was filmed live on October 18, 2025.
• Reverse-image searches found the same footage published that day by multiple outlets with no earlier instances.
• Geolocation placed the scene along Tremont Street by Boston Common, aligning with images captured from other angles.
• The claim that the network aired 2017 video gained traction on X after Grok told users the clip came from an older protest.
• TF1 notes Grok has previously contributed to disinformation, with the episode unfolding against the backdrop of large nationwide ‘No Kings’ demonstrations and a satirical video response from President Trump.
