Iran is responsible for emails meant to intimidate American voters and sow unrest in multiple states while Tehran and Moscow also obtained voter registration with the goal of interfering in the presidential election, US officials said at a rare news conference on Wednesday night – just two weeks before the vote.
John Ratcliffe, the intelligence director, and US Federal Bureau of Investigation director Chris Wray said the US would impose costs on any foreign countries interfering in the 2020 US election.
Despite the Iranian and Russian actions, they said Americans could be confident that their vote would be counted.
“These actions are desperate attempts by desperate adversaries,” Mr Ractliffe said.
The news conference was held as Democratic voters in at least four battleground states, including Florida and Pennsylvania, received threatening emails, falsely purporting to be from the far-right group Proud Boys, that warned “we will come after you” if the recipients did not vote for President Donald Trump.
The voter-intimidation operation apparently used email addresses obtained from state voter registration lists, which include party affiliation and home addresses and can include email addresses and phone numbers.
Those addresses were then used in an apparently widespread targeted spamming operation.
The senders claimed they would know which candidate the recipient was voting for in the November 3 election, for which early voting is ongoing.
