A swimming news site, SwimSwam, first reported Keller’s presence at the Capitol riot on Monday. The video had been circulating in the swimming community since last week, and several people who saw it are said to have reported Keller to the authorities.
Efforts to reach Keller were unsuccessful.
Few of the people who recognized Keller in the video expressed surprise at his presence in Washington. His deleted social media accounts, several of them said, had in recent years included a stream of pro-Trump messaging.
No video has emerged of Keller participating in any violent acts in the Capitol, but his mere presence in the building, if confirmed by the authorities, may have placed him in legal jeopardy. Numerous people who entered the building now face federal charges that include unlawful entry and disorderly conduct. More serious charges include theft of government property and firearms violations.
