Underneath Their Robes is a popular blog about the federal judiciary, written in a gossipy style by the hitherto anonymous Article III Groupie. A3G refers to herself in the feminine voice, but, as Jeffrey Toobin reports today in The New Yorker, A3G is actually David B. Lat, an assistant U.S. attorney in New Jersey. “Although he intended to remain anonymous,” Toobin writes, “the success of the blog made coming clean irresistible.”
