The FBI says it has found no evidence of criminality in a new batch of Hillary Clinton emails, boosting her campaign two days before the election.

FBI Director James Comey told Congress his agency's review had found nothing to alter its original conclusion.

In July, he said Mrs Clinton had been careless but not criminal in handling sensitive material on her private email server while secretary of state.

The issue flared up again with the discovery of new "pertinent" emails.

They were reportedly found on the laptop of Anthony Weiner, the estranged husband of one of the Democratic presidential candidate's closest advisers.

Mr Comey's letter to Congress late last month, revealing the bureau's inquiry into Mrs Clinton's emails had been revived, shook up the White House race and reinvigorated the campaign of Republican nominee Donald Trump.

It was much ado about nothing, but it certainly amounted to something. While FBI Director James Comey, in effect, said "never mind" with regards to Hillary Clinton's emails, for the past two weeks the story has dominated the political conversation, and Democrats have paid a price.

While Mrs Clinton's presidential hopes have stabilised, talk of a possible rout - and sweeping down-ballot victories in congressional races - are a distant memory.

Mrs Clinton will now try to focus on her closing campaign message. Donald Trump almost certainly will continue to accuse his opponent of corruption and, perhaps, again allege the FBI is covering for her.

With only two days until voting, the dust kicked up by this story won't have fully settled by the time Americans head to the polls.

Once this election is over, there should be serious soul-searching within the FBI and the media about how this saga played out. The nation's top law-enforcement agency was a source of constant leaks, as internal disputes spilled into public view.

If Mr Trump wins, many on the left will blame Mr Comey for the result. If Mrs Clinton prevails, she likely will bear a lasting grudge over this political near-miss.

How FBI email verdict affects election

The FBI director had announced that the agency would investigate if the newly discovered messages contained classified information.

But in Sunday's follow-up, Mr Comey wrote: "Since my letter, the FBI investigative team has been working around the clock to process and review a large volume of emails from a device obtained in connection with an unrelated criminal investigation.

"During that process, we reviewed all of the communications that were to or from Hillary Clinton while she was Secretary of State.

"Based on our review, we have not changed our conclusions that we expressed in July with respect to Secretary Clinton."

On board the candidate's campaign airplane, her team said they were always confident of the outcome.

Communications director Jennifer Palmieri told media: "We're glad this matter has been resolved."

But the Trump team cried foul.

Newt Gingrich, an adviser to the Republican nominee, tweeted: "Comey must be under enormous political pressure to cave like this and announce something he cant [sic] possibly know."

Trump campaign manager Kellyanne Conway tweeted: "If FBI conclusions remain unchanged, that means she still was reckless & careless, still lied about classified info, lied re: # of devices."

Campaigning in Minnesota on Sunday, Mr Trump made no mention of Mr Comey's findings.

But he did say Mrs Clinton "will be under investigation for a long, long time, likely concluding in a criminal trial".

He also renewed his claims that the Democrat was being "protected by a rigged system".

The FBI has already established Mrs Clinton had classified information on a private email server that was run out of her upstate New York home.

Mr Comey said in July that her handling of sensitive material during her 2009-13 tenure as secretary of state was "extremely careless", but cleared her of criminal wrongdoing.

The revelation that she handled sensitive information while breaking federal rules by running her own email server has dogged her campaign since last year.

A new NBC/Wall St Journal opinion poll on Sunday before news broke of the FBI letter suggested a four-point lead for Mrs Clinton.

The latest Washington Post/ABC tracking poll put her lead at five points.

Sunday's campaign stops take her to Ohio, Michigan, Pennsylvania and New Hampshire.

Also on Mr Trump's itinerary were Iowa, Michigan, Pennsylvania and Virginia.

Who will win? Play our game to make your call </s> WASHINGTON (JTA) — A renewed investigation into whether Hillary Clinton or her aides mishandled classified information reportedly arose out of the FBI probe of whether Anthony Weiner sexted with an underage girl.

James Comey, the FBI director, on Friday wrote to the chairman of congressional oversight committees that the “FBI has learned of the existence of emails that appear to be pertinent to the investigation” into the private server Clinton used when she was secretary of state.

He said the revelation came about because of an “unrelated case” but did not detail it further. The New York Times, followed by other media outlets, quoted sources as saying that the new emails were uncovered in their probe into Weiner, a former congressman who also ran for mayor of New York.

Weiner, who is Jewish and who was close to the right-wing pro-Israel community while in Congress, is married to a top aide to Clinton, Huma Abedin. They separated this summer when it was revealed that his habit of sexting, or exchanging lascivious images and narratives, which drove him out of Congress and then scuttled his bid for mayor, was continuing unabated. It was subsequently alleged that he was in a sexting relationship with a 15-year old girl in North Carolina, which led to the federal investigation.

Comey had previously closed the inquiry into the Democratic presidential nominee’s server, saying she had mishandled information by using a private server – a result of Clinton’s determination to keep some exchanges quiet – but that nothing rose to the level of a criminal complaint.

Donald Trump, Clinton’s Republican rival, seized on the revelation, praising the FBI at a rally, and saying “We must not let #CrookedHillary take her CRIMINAL SCHEME into the Oval Office” on Twitter.

John Podesta, Clinton’s campaign manager, fired out a statement calling on the FBI to reveal more about the emails, saying the campaign was certain there was nothing in the emails that would implicate Clinton.

“It is extraordinary that we would see something like this just 11 days out from a presidential election,” Podesta said. “The Director owes it to the American people to immediately provide the full details of what he is now examining. We are confident this will not produce any conclusions different from the one the FBI reached in July.” </s> Hours after Federal Bureau of Investigation Director James Comey rattled the world with the revelation he had discovered previously unknown emails related to its probe of Hillary Clinton’s private server, the former secretary of state’s campaign demanded he release the content of those messages to the public—messages reportedly found in the inbox of none other than Anthony Weiner.

Three months after determining Clinton’s use of a “homebrew” server while at the State Department had been “reckless” but not criminal, Comey penned a letter to Congress announcing his office had recovered further messages “that appear to be pertinent to the investigation.” The New York Times reported the FBI had found those emails on devices belonging to former Congressman Anthony Weiner and his estranged wife, vice chairwoman of Clinton’s campaign, amid a separate investigation into the lascivious one-time mayoral candidate’s alleged sexting with a minor.

“FBI Director Comey should immediately provide the American public more information than is contained in the letter he sent to eight Republican committee chairmen,” demanded Clinton campaign chairman John Podesta, no stranger to emails himself, in a statement to the press. “The director owes it to the American people to immediately provide the full details of what he is now examining. We are confident this will not produce any conclusions different from the one the FBI reached in July.”

Podesta also acknowledged the potential of the news to jar the impending presidential election, in which most projections currently show Clinton beating Donald Trump handily.

“It is extraordinary that we would see something like this just 11 days out from a presidential election,” wrote Podesta.

The Clinton operative’s calls echo those made by Trump’s running mate, Indiana Gov. Mike Pence.

“We call on the FBI to immediately release all emails pertinent to their investigation,” the Republican understudy tweeted earlier today. “Americans have the right to know before Election Day.”

Trump himself gloated over the findings at a rally in New Hampshire this afternoon.

“I need to open with a very critical breaking news announcement. The FBI has just sent a letter to Congress informing them that they have discovered new emails pertaining to former Secretary of State Hillary Clinton’s investigation,” the Queens-born businessman told the roaring audience. “Hillary Clinton’s corruption is on a scale we have never seen before. We must not let her take her criminal scheme into the Oval Office.”

Trump and his fellow Republicans had previously disparaged Comey—a member of their party—and his office’s investigation into the server as somehow compromised or “rigged.”

There is at present no evidence Clinton attempted to conceal the newfound correspondence, nor that the FBI has formally reopened its investigation, nor that anything in the emails is incriminating to anyone.

A protege of Sen. Charles Schumer and a friend to the Clintons, Weiner once appeared among the rising lights of New York City politics. Then, in 2011, he accidentally posted a partially nude photo of himself on Twitter while sharing explicit images with several women.

He resigned his Brooklyn-Queens seat, but then attempted to return from the political grave with a run for mayor in 2013. He briefly led the field in the Democratic primary, until it again surfaced that he had sent even more lewd messages to three more women.

The fallen pol ultimately placed fifth in the race, well below now-Mayor Bill de Blasio. Abedin remained beside him through each humiliation.

Then, in August, the New York Post published images Weiner had apparently sent to yet another woman—one of which pictured his five-year-old son cuddled up near his visibly erect member. In the thick of the campaign season, Abedin finally announced she would leave her husband.

The situation deteriorated further for the ex-congressman when the United Kingdom’s Daily Mail published sexualized online correspondence between Weiner and a 15-year-old girl. This, reportedly, is what triggered the FBI investigation.

Disclosure: Donald Trump is the father-in-law of Jared Kushner, the publisher of Observer Media. </s> President Donald Trump fired FBI Director James Comey Tuesday evening, dismissing the former bureau chief in a letter addressing him directly.

"I have received the attached letters from the Attorney General and Deputy Attorney General of the United States recommending your dismissal as Director of the Federal Bureau of Investigation," the President wrote to Comey. "I have accepted their recommendation and you are hereby terminated and removed from office, effective immediately.

"While I greatly appreciate you informing me, on three separate occasions, that I am not under investigation, I nevertheless concur with the judgement of the Department of Justice that you are not able to effectively lead the Bureau," Trump added.

"It is essential that we find new leadership for the FBI that restores public trust and confidence in its vital law enforcement mission."

Comey's firing came not long after the FBI told the Senate Judiciary committee that Comey had misspoken during his testimony about Hillary Clinton aide Huma Abedin forwarding thousands of emails to her husband, former Congressman Anthony Weiner. </s> Hillary Clinton’s campaign lashed out at the FBI on Saturday, saying there was no indication that a cache of recently discovered emails under review by the agency was connected to the Democratic nominee. Barnstorming the West, Republican rival Donald Trump pounced on the reignited email controversy.

Clinton campaign chairman John Podesta told reporters FBI Director James Comey’s letter to Congress about the new emails was “long on innuendo” and “short on facts.”

“There’s no evidence of wrongdoing,” he said. “No charge of wrongdoing. No indication this is even about Hillary.”

But on that latter point, Comey in fact said the new trove was “pertinent” to the Clinton email investigation, without explaining how.

A government official told The Associated Press on Saturday that the Justice Department had advised the FBI against telling Congress about the new developments in the Clinton investigation because of the potential fallout so close to the election. The official was not authorized to speak publicly about the matter and discussed it on condition of anonymity.

Justice officials concluded the letter would be inconsistent with department policy that directs against investigative actions that could be seen as affecting an election or helping a particular candidate, the official said.

Landing with a thud, the email issue again threatened to undermine an advantage built by Clinton, the Democratic nominee, over Trump and raised the possibility that the Republican might be able to seize momentum during the final days before the Nov. 8 election.

Trump told a crowd in Golden, Colorado, on Saturday that the FBI’s review of Clinton email practices raises “everybody’s deepest hope that justice, as last, can be properly delivered.” His crowd cheered Clinton’s email woes, which Trump has taken to calling the biggest political scandal since Watergate.

Trump also had battleground Arizona on his plate Saturday. Early voting has been underway for weeks and Clinton, who was campaigning Saturday in Florida, has led in preference polls, both nationally and in key swing states.

The FBI is looking into whether there was classified information on a device belonging to Anthony Weiner, the disgraced ex-congressman who is separated from longtime Clinton aide Huma Abedin. Comey, in his letter to Congress on Friday, said the FBI had recently come upon new emails while pursuing an unrelated case and was reviewing whether they were classified.

The announcement raised more questions than answers and generated criticism that Comey was injecting a significant development too close to an election. Yet the FBI director also faced the prospect of intense scrutiny if voters learned that he had been sitting on a major development until after the election.

Podesta and campaign manager Robby Mook spoke to reporters in a conference call, following Clinton’s hastily arranged news conference on Friday night in a high school choir room in Des Moines, Iowa. In it, she said “the American people deserve to get the full and complete facts immediately. The director himself has said he doesn’t know whether the emails referenced in his letter are significant or not.”

But long-term, the development all but ensured that, even should Clinton win the White House, she and several of her closest aides would celebrate a victory under a cloud of investigation. </s> WASHINGTON — The presidential campaign was rocked on Friday after federal law enforcement officials said that emails pertinent to the closed investigation into Hillary Clinton’s private email server were discovered on a computer belonging to Anthony D. Weiner, the estranged husband of a top Clinton aide.

In a letter to Congress, the F.B.I. director, James B. Comey, said the emails had surfaced in an unrelated case, which law enforcement officials said was an F.B.I. investigation into illicit text messages from Mr. Weiner to a 15-year-old girl in North Carolina. Mr. Weiner, a former Democratic congressman from New York, is married to Huma Abedin, the top aide.

Mr. Comey's letter said that the F.B.I. would review the emails to determine if they improperly contained classified information, which is tightly controlled by the government. Senior law enforcement officials said that it was unclear if any of the emails were from Mrs. Clinton’s private server. And while Mr. Comey said in his letter that the emails “appear to be pertinent,” the F.B.I. had not yet examined them. </s> (CNN) FBI Director James Comey told lawmakers Sunday the agency hasn't changed its opinion that Hillary Clinton should not face criminal charges after a review of new emails.

"Based on our review, we have not changed our conclusions that we expressed in July," Comey wrote in the new letter to congressional committee chairmen.

Comey dropped a bombshell on the presidential race last month when he sent a letter to Congress saying the FBI had discovered emails in a separate investigation that could be connected to the now-closed probe of whether Clinton mishandled classified information. The move infuriated Democrats and emboldened Republican nominee Donald Trump.

It's impossible to know before results are tallied what impact Comey's actions -- first raising a vaguely worded red flag 11 days out, and then lowering it two days from the election -- will have on the contest. But the news could help Clinton put to rest a controversy that has dogged her in the 2016 race's closing days, helping Trump narrow a polling gap nationally and in key battleground states.

Trump assailed the FBI's handling of the matter, though he did not directly address Comey's announcement at a rally in Sterling Heights, Michigan.

"You can't review 650,000 new emails in eight days. You can't do it, folks," Trump said, adding, "Hillary Clinton is guilty. She knows it, the FBI knows it, the people know it, and now it's up to the American people to deliver justice at the ballot box on November 8."

Dianne Feinstein, the top Democrat on the Senate Select Committee on Intelligence, blasted Comey's handling of the review.

"Today's letter makes Director Comey's actions nine days ago even more troubling," Feinstein said in a statement. "There's no doubt that it created a false impression about the nature of the agency's inquiry."

She added: "The Justice Department needs to take a look at its procedures to prevent similar actions that could influence future elections."

'As fast as we could'

Comey's letter was the culmination of a fast-paced review of the newly discovered email, law enforcement sources said Sunday.

"We went through this as fast as we could," a senior law enforcement official told CNN, with another law enforcement official saying investigators worked "around the clock" to review the large volume of emails.

The FBI found the new emails as part of its separate investigation into a sexting incident by Anthony Weiner, the estranged husband of top Clinton aide Huma Abedin.

The thousands of new emails were mostly personal and duplicates of what had already been seen, law enforcement officials said in explaining how the conclusion was reached so quickly. The laptop which was found was about a decade old with lots of personal content on it not relevant to the investigation, according to one source.

The probe is considered over with regard to Clinton. Though with not all the deleted emails recovered and not all the devices in FBI's possession, it is always possible something else could turn up that would require more review.

There were some classified emails found, but law enforcement officials stressed the issue is not the classified information so much as proving intent. The sources would not specify if the the classified messages were new or duplicates of ones already reviewed, nor would would officials say how many there were and what levels at which they were classified.

"Keep in mind we are focused on intent," the official said. "We know there are classified materials, but that doesn't change the conclusion reached back in July."

As for others who were part of the probe, including Abedin, the FBI is still working on some remaining aspects of the review, including determining how the emails ended up on the laptop in the first place. Abedin's attorneys have said she doesn't know why these emails were there because this wasn't a computer she used.

JUST WATCHED Who is Huma Abedin? Replay More Videos ... MUST WATCH Who is Huma Abedin? 03:25

The expectation remains that investigators will have to talk to Abedin again.

It isn't uncommon to come across new evidence after concluding a probe -- which is what happened here in October. Normally, investigators take a look to see if anything changes in their conclusions and it's not a controversial issue. This case isn't a normal case, given the election and the stakes.

DOJ informed of decision

Comey sent the letter as soon as possible, the senior law enforcement official said. He was "very careful" about how the letter was crafted given the sensitivities.

Attorney General Loretta Lynch was informed ahead of time that the FBI director was sending the updated letter to Congress informing them of that there would be no change in the FBI stance on Hillary Clinton, a Justice official told CNN on Sunday.

Lynch and Deputy Attorney General Sally Yates disagreed with Comey's earlier decision to notify Congress. The attorney general backed Comey's move Sunday.

"Everyone is on the same page," the source said.

Since there is no change to the original findings, the Justice Department has no need to weigh in further, the official said.

"The Department of Justice and the FBI dedicated all necessary resources to conduct this review expeditiously," the Justice Department said in a brief statement released Sunday afternoon.

Campaigns weigh in

Clinton spokesman Brian Fallon said her campaign is validated in its belief that nothing would change.

We were always confident nothing would cause the July decision to be revisited. Now Director Comey has confirmed ithttps://t.co/BMQQx9eRzw — Brian Fallon (@brianefallon) November 6, 2016

"We were always confident nothing would cause the July decision to be revisited. Now Director Comey has confirmed it," he tweeted.

The Trump campaign quickly slammed Comey.

"We thought that Director Comey and the FBI were wrong when they made their initial recommendation in July, and we think that they're wrong now," Trump spokesman Jason Miller told CNN's Wolf Blitzer on "The Situation Room."

GOP vice presidential nominee Mike Pence sought to keep the pressure on Clinton.

"Mishandling classified information is a crime," he said at a rally in an airport hanger in Hickory, North Carolina. "Hillary Clinton said that she never sent or received any classified information and the director of the FBI told the Congress classified information was sent."

In Michigan, Trump called Clinton "the most corrupt person ever to seek the office of the presidency of the United States."

But the Republican nominee, who has expressed hope in the last week that the FBI's review of new emails might yield an indictment, emphasized to his supporters Sunday that Clinton is "protected" by powerful forces.

"Well, you have to understand it's a rigged system and she's protected," Trump said in Minnesota, though he offered no evidence to back up his theory.

'It opened a wound'

A senior Democrat close to Clinton's campaign told CNN that "it's impossible to fully undo the damage of the last nine days."

Internal campaign polling, the source said, found that some independents and Republican women fled Clinton after the original Comey announcement, robbing her of a constituency that she'd hoped would turn her contest with Trump into a blowout.

"It opened a wound that cannot be quickly healed," the Democrat said.

However, the Democrat called it a relief that the "matter is resolved" and said Clinton's campaign plans to "make everyone know about" Comey's Sunday letter.

Comey's last-minute announcement gives Clinton an opportunity for an I-told-you-so moment.

"We have seen Director Comey's latest letter to the Hill," said Jennifer Palmieri, Clinton's communications director, speaking with reporters after the news broke. "We are glad to see that he has found, as we were confident that he would, that he had confirmed the conclusions he reached in July and we are glad that this matter is resolved."

Trump and his allies have seized on that announcement, using it to claim Clinton was likely to face criminal charges.

"If she were to win, it would create an unprecedented constitutional crisis," Trump claimed Saturday night in Reno, Nevada. "In that situation we could very well have a sitting president under felony indictment and ultimately a criminal trial. It would grind government to a halt."

Political benefit

The political benefit for Trump has been that Republicans who'd been skeptical of their party's nominee have largely followed vice presidential nominee Mike Pence's calls to "come home" to the party -- finding Trump less objectionable than Clinton.

It's not just Trump's campaign that seized on Comey's actions. Down-ballot Republicans -- particularly Senate candidates who had been forced to answer for Trump's statements for months -- used the moment to change the topic, shifting to the more comfortable ground of attacking Clinton.

The last-minute Sunday move from Comey could also provide new fuel for Trump's claims of a "rigged" system -- allowing him to cast the FBI director's intervention in the presidential election in a new light.

Comey and the FBI went from Trump's scapegoat to the Republican nominee's hero, with Trump claiming Comey had redeemed himself just in time.

Newt Gingrich, a top Trump ally, tweeted "Comey must be under enormous political pressure to cave like this."

Comey must be under enormous political pressure to cave like this and announce something he cant possibly know. — Newt Gingrich (@newtgingrich) November 6, 2016

Dems, GOP react

House Speaker Paul Ryan dismissed the significance of Comey's latest letter.

"Regardless of this decision, the undisputed finding of the FBI's investigation is that Secretary Clinton put our nation's secrets at risk and in doing so compromised our national security," Ryan said in a statement. "Fortunately, the American people have the opportunity to ensure Secretary Clinton never gets her hands on classified information again."

Capitol Hill Democrats praised Comey's decision to release more information.

"While the original letter should never have been sent so close to an election, the expeditious review of these emails should put to rest -- once and for all -- the irresponsible speculation indulged in by the Trump campaign and others," Rep. Adam Schiff, the top Democrat on the House Intelligence Committee said. "Voters can now make their decision based on the merits, and that decision should be simple: it is the choice between a woman superbly qualified to be commander in chief, and a man patently unfit for office."

Republican National Committee Chairman Reince Priebus issued a statement saying, "None of this changes the fact that the FBI continues to investigate the Clinton Foundation for corruption involving her tenure as secretary of state. Hillary Clinton should never be president." </s> Hillary Clinton lashed out Saturday at the FBI's handling of a new email review, leading a chorus of Democratic leaders who declared the bureau's actions just days before the election "unprecedented" and "deeply troubling." Emboldened Republican rival Donald Trump seized on the reignited email controversy, hoping to raise new doubts about Clinton's trustworthiness.

Rallying supporters in Florida, Clinton pressed FBI Director James Comey to put out the "full and complete facts" about the review into a cache of recently discovered emails. Clinton backers panned Comey's letter to Congress about the new emails as severely lacking crucial details.

"It is pretty strange to put something like that out with such little information right before an election," Clinton said. She accused Trump of using the issue to confuse and mislead voters in the final leg of the campaign for the Nov. 8 election.

The controversy over Clinton's email practices at the State Department has dogged her for more than a year. The former secretary of state has often been reluctant to weigh in on the matter — and defensive when she's been pushed to do so.

But Clinton's approach to this latest flair-up is markedly different, underscoring worries that the matter could damage her standing with voters in the election's final days. Clinton advisers have been rallying Democratic lawmakers and other supporters to her defense, including members of the Congressional Black Caucus.

Earlier Saturday, Clinton campaign chairman John Podesta said there was "no evidence of wrongdoing" in the new email review and "no indication this is even about Hillary." But Comey, who enraged Republicans in the summer when he announced the FBI would not prosecute Clinton for her loose handling of official email, in fact said the new trove appeared to be "pertinent" to the Clinton email investigation. He did not explain how.

A government official told The Associated Press on Saturday that the Justice Department had advised the FBI against telling Congress about the new developments in the Clinton investigation because of the potential fallout so close to the election. The official was not authorized to speak publicly about the matter and discussed it on condition of anonymity.

Justice officials concluded the letter would be inconsistent with department policy that directs against investigative actions that could be seen as affecting an election or helping a particular candidate, the official said.

Landing with a thud, the email issue again threatened to undermine an advantage built by Clinton, the Democratic nominee, over Trump and raised the possibility that the Republican might be able to seize late momentum.

Trump told a crowd in Golden, Colorado, on Saturday that the FBI's review of Clinton email practices raises "everybody's deepest hope that justice, as last, can be properly delivered." His crowd cheered Clinton's email woes, which Trump has taken to calling the biggest political scandal since Watergate.

The FBI is looking into whether there was classified information on a device belonging to Anthony Weiner, the disgraced ex-congressman who is separated from longtime Clinton aide Huma Abedin. Comey, in his letter to Congress on Friday, said the FBI had recently come upon new emails while pursuing an unrelated case and was reviewing whether they were classified.

Trump mused aloud during his rally about whether Clinton was "going to keep Huma," adding that Abedin has "been a problem." He hurled insults at Weiner, warning again that the former congressman posed a national security risk because of his access to information through his estranged wife. Abedin, a close Clinton confidant who is a near constant presence in the campaign, was not traveling with Clinton on Saturday.

The FBI announcement raised more questions than answers and generated criticism that Comey was injecting a significant development too close to an election. Yet the FBI director also faced the prospect of intense scrutiny if voters learned that he had been sitting on a major development until after the election.

New York Rep. Gregory Meeks suggested the FBI chief might be trying to sway the election and called for him to disclose what he knows. Clinton herself said of Comey: "Put it all out on the table."

Long term, the development all but ensured that, even should Clinton win the White House, she would celebrate a victory under a cloud of investigation.

Congressional Republicans have already promised years of investigations into Clinton's private email system. And that's only one of the email-related episodes facing her in the campaign's closing days. The tens of thousands of confidential emails from Clinton campaign insiders that were hacked — her campaign blames Russia — and then released by WikiLeaks have provided a steady stream of questions about her policy positions, personnel choices and ties with her husband's extensive charitable network and post-presidential pursuits.

In his letter to congressional leaders Friday, Comey wrote only that new emails have emerged, prompting the agency to "take appropriate investigative steps" to review information that appeared pertinent to its previously closed investigation into Clinton private email system.

Given a political gift from the FBI, Trump's challenge now becomes avoiding any big missteps that might overshadow Clinton's troubles over the campaign's final days. If history is a guide, that won't be easy.

Inside Trump's Colorado rally, his supporters worried whether he could stick to his message about the emails.
