Environmental groups, a prominent part of Maine Democrat Graham Platner’s base, are withdrawing their endorsement for his Senate run following sexual assault allegations.

Also abandoning Platner are top lawmakers working on energy and environment issues like Sens. Martin Heinrich of New Mexico and Sheldon Whitehouse of Rhode Island.

Platner, an oyster farmer and progressive, won a Democratic primary to take on Republican Sen. Susan Collins in one of the most watched races of the year. But Platner is now considering whether to pursue his candidacy following POLITICO’s reporting of new allegations against him.
