Mr Trump, meanwhile, voiced new confidence as he brought his campaign - and his dark visions of a rigged American economic and political system - to Democratic strongholds.
The new review involved material found on a computer belonging to Anthony Weiner, the disgraced former congressman and estranged husband of Abedin, the Clinton aide.
Campaign manager Kellyanne Conway later told MSNBC "the reason that so many Americans have a problem with Hillary Clinton's honesty, trustworthiness and veracity does not change".
The fresh emails were discovered during a separate FBI investigation into Weiner, a former member of Congress from NY, who is under investigation for allegedly sending explicit images to an underage girl. Communications director Jennifer Palmieri told reporters, "We're glad this matter is resolved", though Clinton herself did not mention the issue during a rally in OH with basketball superstar LeBron James.
"This election is a moment of reckoning", she told voters.Through the day she is also making stops in North Carolina and MI.
That disclosure, made over the objections of the Justice Department, roiled the presidential race in its final days and revived an issue that the Clinton campaign thought had ended over the summer when the investigation closed without charges.
In Florida, votes are pouring in from Miami-Dade county, and the Clinton campaign is boasting that many are from Hispanics thought unlikely to turn out (and therefore don't show up on likely voter surveys).
Huskers moving on after lopsided loss
Only Maryland and a reeling Michigan State stand between the Buckeyes and entering the game vs. the Wolverines with one loss. The Buckeyes sit a game back of MI in the Big Ten East, while the Cornhuskers lead the pack by a game in the Big Ten West.
Christie says he thinks Trump will defeat Democrat Hillary Clinton Tuesday because the momentum is on his side and the country wants change.
She was careful to avoid giving any indication of her preferred victor in the Trump-Clinton showdown.
As campaigning continued ahead of Tuesday's presidential election, a Clinton spokeswoman said the candidate was "glad this matter is resolved".
"I write to supplement my October 28, 2016 letter that notified you the Federal Bureau of Investigation would be taking additional investigative steps with respect to former Secretary of State Clinton's use of a personal email server". Pierre Thomas on the FBI's conclusion coming in late today. Back then, he called Clinton's handling of e-mails careless, but saying no charges in the case. Most show Hillary Clinton up a few points nationally, but numerous battleground states still look close.
Trump kicked off his Election Day eve blitz with a rally Monday in Florida. He already must win almost all of the roughly dozen battleground states. Also joining them in the city of brotherly love will be President Obama and First Lady Michelle Obama.
The president saw the election in part as a vote on his legacy, declaring all that progress goes down the drain if they do not win tomorrow and calling Trump "uniquely unqualified" to be president.
