Rep. Jake Auchincloss (D-MA) became the first elected Democrat to call on scandal-plagued Democrat Graham Platner to drop out of the race for Senate in Maine amid controversy over a tattoo on his chest with Nazi origins and other controversies.

Jewish Insider earlier reported that Platner had on at least one occasion identified the tattoo on his chest as a Nazi SS symbol, known as a “Totenkopf,” to a former acquaintance and had been fully aware of the tattoo and its meaning well before jumping into the race to replace Sen. Susan Collins (R-ME), even bragging about having it. 

Auchincloss urged Platner to abandon his Senate bid on Sunday, telling Politico that he finds the progressive candidate’s conduct “personally disqualifying.” 

Platner has dismissed wrongdoing and claimed he had no idea the tattoo symbol was a Nazi insignia when he got it with fellow Marines while in Croatia in 2007. 

“I am not a secret Nazi. Actually if you read through my Reddit comments, I think you can pretty much figure out where I stand on Nazism and antisemitism,” Platner said on the “Pod Save America” podcast last week.

Auchincloss expressed dissatisfaction with Platner’s defenses, in which the progressive candidate has said his actions aren’t a “liability.”

“I think it’s a liability, and I think we should have high standards for United States senators and one of them is: you don’t have a Nazi tattoo on your body,” Auchincloss told WCVB Channel 5 Boston on Sunday. 

“I hope that Maine voters would agree with me,” Auchincloss said to Politico. “Democrats would be united in condemning a Republican candidate who has this episode, and we should be consistent.”

Platner is running against Gov. Janet Mills in the Democratic primary. The winner will face Collins in what is expected to be a hotly-contested race.

Some progressive members of Congress, led by Sen. Bernie Sanders (I-VT), have defended Platner amid his numerous scandals. 

“He sounds like a human being to me,” Sen. Chris Murphy (D-CT) said of Platner’s tattoo in a CNN interview on Sunday. “A human being who made mistakes, recognizes them, and is very open about it.”
