Democratic National Committee interim chairwoman Donna Brazile has resigned as a commentator for CNN after emails revealed that she assisted the Clinton campaign during the primaries. Brazile had previously taken a leave of absence from the cable news network after the previous DNC boss resigned and she was promoted to top spot.

18 revelations from the Wikileaks hack

Emails released today by Wikileaks show that before a primary debate hosted by CNN in March, Brazile contacted the Clinton campaign to notify them about a question she and her rival, Senator Bernie Sanders, would be asked about the water crisis in Flint, Michigan.

"One of the questions directed to HRC tomorrow is from a woman with a rash," Brazile wrote to senior Clinton staff. "Her family has lead poison and she will ask what, if anything, will Hillary do as president to help the ppl of Flint."

An earlier Wikileaks release had already shown that Brazile had emailed questions to the Clinton camp, ahead of a CNN town hall event.

The bad news for Hillary Clinton is that the polls had already begun to tighten both nationally and in some key battleground states before the FBI announced the new inquiry. 

In the ABC News/Washington Post tracking poll, external for example, Mrs Clinton was ahead of Donald Trump by 12 points on 23 October, but that lead had narrowed to one point a week later. 

Enthusiasm for Mrs Clinton had slipped slightly in that poll, with the number of her supporters who said they were very enthusiastic about her down from 51% to 47%. 

Polls do tend to tighten as election day approaches anyway, but at the moment it's unclear what, if any, effect news of the FBI inquiry will have. 

In a CBS poll, external of 13 battleground states, 52 percent of voters said they expected the emails to contain "more of what we already know" and most of those who said they were less likely to vote for Mrs Clinton were Republicans.

It seems a long time since this presidential campaign put issues front and centre.

We've started a series that kicks off with what's at stake in this election for the Supreme Court. 

And there's a full rundown here of where the candidates stand.

Longtime Clinton aide Huma Abedin has been missing from the campaign trail ever since the news that the FBI had uncovered more Clinton emails during its investigation into her former husband, Anthony Weiner.

The Daily Mail has spotted her this morning dropping her son off at school in Manhattan instead of helping her boss campaign in Ohio, a key swing state.

On Friday the Washington Post came out with the latest from its long-running investigation, external into Trump's charitable donations.

In its latest story, the paper called 420-plus charities with some connection to Trump but found only one personal gift from him between 2008 and the spring of this year. 

But the Post did find nearly $8m that Trump has donated from his own pocket since the early 1980s.

One of the bizarre episodes the paper recounts is that in 1996, Trump showed up without an invitation to a charity for the Association to Benefit Children where he took a seat on the stage that had been reserved for a major donor, despite not being a donor himself.

In response the piece, the Trump campaign told the Post that he "has personally donated tens of millions of dollars... to charitable causes".

Commentators believe this campaign has been the biggest fear-mongering campaign of the modern presidential age.

Here's why:

The Clinton campaign has reprised the classic 1964 attack ad "Daisy" made famous during the presidential campaign of Lyndon Johnson, about nuclear war fears.

The original actress, who was just a toddler when the ad was first filmed, reappears to talk about her concerns that a Trump presidency could lead to a nuclear war. 

 "The fear of nuclear war that we had as children - I never thought our children would ever have to deal with that again," says actress Monique Corzilius Luiz. 

 "And to see that coming forward in this election is really scary."

In the weekend since the FBI's bombshell announcement - only 11 days before the election - pollsters have frantically been trying to determine how the revelation has affected the candidates. 

Only now are we getting reliable numbers. One poll, external taken by Politico magazine shows very little change in the candidates' polling. They still find Clinton with a three-point edge nationally over Trump, who has been making ground since the third debate. Most respondents (nine out of 10) had heard of the latest FBI probe - with Politico's polling researcher adding "that's the highest level of awareness for any issue we have tested". 

More than 80% of Republicans agreed with the Trump statement that the email scandal is "bigger than Watergate" and 45% of the total respondents agreed as well.

A key figure in all this is James Comey, the FBI director, who went public with the news of the new emails despite guidance from the Department of Justice not to do so.

He has argued that he had to inform Congress for the sake of transparency.

But the Clinton campaign are furious and say the information he has made available is too scant.

Who is James Comey?

The news that the FBI has found more emails that could be related to their investigation of Hillary Clinton's private email arrangements has provided an unexpected jolt to the presidential race.
