Dozens of voters in a heavily Democratic county in Florida and across several states reported receiving emails on Thursday purporting to come from a right-wing group threatening to “come after” them unless they vote for President Trump. But an examination of the messages, which are now under investigation by state and federal authorities, shows they were sent via servers located overseas, raising questions about their origin amid concerns about voter intimidation just two weeks before Election Day. Democratic voters in Alachua County, Florida, began receiving the email on Tuesday morning, and voters in Alaska and Arizona also reported receiving the message. Early voting began in Florida on Monday. The emails appeared to come from the right-wing group The Proud Boys, and showed a “from” address of email@example.com. The Proud Boys has been designated a hate group by the Southern Poverty Law Center, a civil rights advocacy group.
