According to screen captures posted by users on social media, Kellyanne Conway’s account (@KellyannePolls) shared an image of her topless teenage daughter using Twitter’s recently launched Fleets feature, which deletes posts after a 24-hour period (similar to Instagram and Snapchat’s stories). The Fleet was removed but not before Twitter users documented it.
On TikTok, Claudia Conway on Monday posted videos confirming that the picture was authentic; those have since been deleted from her TikTok account but Twitter users reposted copies of the videos. In the videos, a visibly upset Claudia Conway speculated that her mother may have accidentally posted the image.
