Rep. Jake Auchincloss (D-MA) has refused to endorse Graham Platner, the Democratic nominee for U.S. Senate in Maine, citing Platner's tattoo resembling a Nazi Death’s Head symbol and related commentary as disqualifying. Platner obtained the tattoo in his twenties while serving as a Marine and has stated he was unaware of its historical associations. After Janet Mills withdrew from the race, Platner became the sole Democratic candidate and will face incumbent Sen. Susan Collins (R-ME) in the general election.
