PARRISH, Fla. — Adam Johnson poured Scotch into a coffee mug, logged on to Zoom and steeled himself for his plea hearing. He concentrated on looking contrite.
Johnson was among the most infamous of the Donald Trump supporters who had roamed the halls of the U.S. Capitol on Jan. 6, 2021. He’d found House Speaker Nancy Pelosi’s lectern and was carrying it into the Rotunda when he waved to a news photographer and flashed an impish grin. He’d gone viral, becoming an instant meme in a Trump knit hat.
