The Democratic candidate maintains only 5 point lead over the Republican nominee
Hillary Clinton's election lead over Republican rival Donald Trump has been cut almost in half by the revelation that the FBI is investigating new emails sent during her time as Secretary of State.
The Democrat's lead slumped from 4.6 percentage points on Friday to 2.5 points late on Monday, according to the Real Clear Politics tracker which averages most major polls.
The FBI said on Friday that it had found thousands of emails, during an unrelated investigation, that may be "pertinent" to its review of Ms Clinton's use of a private server from 2009 to 2013.
A Reuters survey conducted in the midst of the FBI's announcement showed Ms Clinton on 44 per cent of the vote to Mr Trump's 39 per cent, already slipping slightly from a six-point lead.
But that poll may not yet represent the full impact of the damage from FBI director James Comey's letter to Congress, that his agency was looking into new emails uncovered during an unrelated investigation into Anthony Weiner, the estranged husband of top Clinton aide Huma Abedin.
Clinton campaign manager Robby Mook decried what he called a "blatant double standard" following a CNBC report that FBI Director James Comey opposed releasing details about possible Russian interference in the US election because it was too close to Election Day. The FBI declined to comment on that report on Monday.
