Ballot drop boxes, long a target of misinformation, face physical threats

With Election Day nearing, authorities in Oregon and Washington have opened investigations and stepped up security measures after two ballot drop boxes were set ablaze on Monday. 

Three ballots were damaged after an incendiary device was found inside a ballot box in Portland, Oregon, on Monday. And on the same day, officials feared hundreds of ballots were damaged by a fire in a ballot box in nearby Vancouver, Washington. Police said a "suspicious device" was found next to the box. 

Ballot drop boxes have historically been targets of misinformation, according to experts, who say the false claims surged in 2020 when then-President Donald Trump raised doubts about the security of mail-in ballots. Drop boxes are now facing growing physical threats, according to election officials and internal U.S. government warnings.
