American officials have claimed that Iran is responsible for emails meant to intimidate American voters and sow unrest in multiple states. The FBI and Intelligence chiefs, at a press conference said that Tehran and Moscow have also obtained voter registration with the goal of interfering in the election. The officials added that the US will impose costs on any foreign countries interfering in the 2020 US election. Democratic voters in at least four battleground states have received threatening emails, purporting to be from the far-right group Proud Boys, that warned the recipients of consequences if they didn't vote for President Donald Trump.
