The man pictured in a viral photo cradling the lectern of Speaker Nancy Pelosi during the raid Wednesday of the U.S. Capitol was arrested by U.S. Marshals on Friday night in Florida. The photo of Adam Johnson, of Parrish, Fla., quickly circulated online in the wake of the mob attack. It showed Mr. Johnson sporting a wide smile as he waved to the camera with one hand and hauled off the lectern with the other. On his head was a Trump cap, with the number “45” on the front.
