SCARBOROUGH, Maine (AP) — The Maine Democratic Party on Wednesday voted to hold a convention now that Democratic Graham Platner has announced he’ll drop out of the state’s U.S. Senate race after a former girlfriend accused him of sexual assault.

Platner, who denies the allegation, faced considerable pressure from his own party to quit the race. The first-time candidate also has been accused of trying to influence how his replacement is selected — a claim he also denied.

Platner’s planned departure have left a crucial U.S. Senate race unsettled just months before the November midterm elections. The Maine Democratic Party, which by law is responsible for naming a replacement, announced it’ll move forward with holding a nominating convention to choose a new nominee.
