Hillary Clinton is now leading by 3% against Donald Trump in the US presidential race, according to a CBS poll.
At the beginning of this week Clinton was down in the polls, with some suggesting the shock turnaround which gave Trump a slight advantage was due to the FBI's revelation that it is investigating a tranche of her emails.
Last week the Democratic candidate had a 14-point lead in a poll from Associated Press-GfK, but the poll released earlier this week suggested this advantage had been completely wiped out.
Trump has made great play of the email scandal in his own campaign, and referred to his Democratic rival as "Crooked Hillary".
The election will take place next Tuesday, so there is still time for the polls to change again yet.
