Authorities in Maine are investigating an allegation that dozens of unmarked ballots that were to be used in this November's election arrived inside a woman's Amazon order.

The town of Ellsworth reported to the state last week that it was missing a shipment of 250 absentee ballots, Secretary of State Shenna Bellows said Monday. That happened the same day a woman in Newburgh, 42 miles away, reported finding bundles of ballots — 250 in all — wrapped in plastic inside the box that contained her delivery from Amazon.

The secretary of state's law enforcement division is investigating the discovery with assistance from other state and federal authorities, Bellows said during a news conference at the state Capitol. She declined to identify the person who reported the ballots inside the delivery box.

“I have full confidence that law enforcement will determine who is responsible, and any bad actor will be held accountable," she said, suggesting there could be other examples.

“This year, it seems that there may have been attempts to interrupt the distribution of ballots and ballot materials,” Bellows said, declining to elaborate.
