The day before Maine's Democratic Senate primary in June, a CBS News reporter asked Sen. Bernie Sanders, I-Vt., whether he still supported the left-wing populist candidate Graham Platner in light of the controversies surrounding him. At the time, they included a tattoo that resembled a Nazi symbol (which he covered up in response to criticism after it was revealed), a history of inflammatory and bigoted comments on social media, and allegations that he mistreated romantic partners.
