Steven D'Antuono, formerly in charge of the FBI's Washington field office, told the House Judiciary Committee in closed-door testimony that while his field office knew some of their informants would be at Donald Trump's "Stop the Steal" rally across town, informants from other field offices were present at the Capitol that day, as well as other informants who had participated on their own accord.

One fed informant was on the phone with his handler as he breached the Capitol.
