Sen. John Fetterman (D-PA) on Monday called for Sen. Bernie Sanders (I-VT) to rescind his endorsement of embattled Democratic Maine Senate candidate Graham Platner following sexual assault allegations.

Sanders has stood by Platner through a slew of controversies, including those that allege Platner has a pattern of violence against women, but as of Monday, the socialist senator has not joined top Democrats in withdrawing support of the Senate hopeful.
