Fresh source coverage has been added to this developing story, but the central facts remain unchanged: the Democratic Senate nominee in Maine has withdrawn his campaign after former partners made allegations of sexual assault. He had been polling ahead of the Republican incumbent, Senator Susan Collins, and his rapid loss of party endorsements marks a serious blow to Democratic hopes of capturing a competitive seat in the state.

The collapse has drawn scrutiny of how Maine Democrats vetted the candidate before nominating him, with senior party figures criticising the apparent failure to examine his background. Accusers have separately criticised the handling of the allegations by major news outlets, including The New York Times. Party officials are now searching for a replacement nominee, with several members and public figures being urged to consider running.
