US Election 2016

The Democratic presidential candidate called on the FBI director to explain the new inquiry to the American people.

James Comey earlier said the FBI was looking into newly found messages.

The latest emails came to light during a separate inquiry into top Clinton aide Huma Abedin's estranged husband, former congressman Anthony Weiner.

Devices belonging to Ms Abedin and Mr Weiner were seized in an investigation into whether he sent sexually explicit emails to a 15-year-old girl in North Carolina.

He also suggested the presidential race was looking like a "rigged election".

The comments came in the wake of the publication of a recording in which he made obscene remarks, which sparked a string of sexual assault claims.

Polls suggest Mr Trump is losing ground in some of the key battleground states.

Speaking at a rally in New Hampshire, Mr Trump said Mrs Clinton had been "all pumped up" at the beginning of the last debate but could "barely reach her car" at the end.

Former Apprentice contestant Summer Zervos said the businessman forced himself on her at a Los Angeles hotel and began "thrusting his genitals".

Kristin Anderson told the Washington Post he reached up her skirt and groped her in a New York club in the 1990s.

The Republican nominee branded the allegations as "lies and smears".

Ms Anderson, now 46, said the property mogul touched her through her underwear at a Manhattan nightspot when she was a waitress trying to make it as a model.

She said she was "very grossed out and weirded out".

The Republican presidential nominee said the women making the allegations were "horrible liars" and the media was colluding with rival Hillary Clinton.

Several women say he groped them or forcibly kissed them.

First Lady Michelle Obama earlier said Mr Trump's boasts about groping women were "shocking and demeaning".

"Leaders should meet a basic standard of human decency," she said during a campaign appearance in New Hampshire.

Two women told the New York Times that the Republican presidential runner groped or kissed them.

A reporter for People magazine wrote a first person account describing being forcibly kissed by the property tycoon.

The comments were made in an alleged April 2011 exchange between Clinton communications director Jennifer Palmieri and a think tank fellow.

Her then-colleague appears to mock media mogul Rupert Murdoch for bringing up his children as Catholics.

Republican House Speaker Paul Ryan said the comments were "staggering".

Email leak shows Clinton aides infighting

The exchange was revealed this week among thousands of emails disclosed by WikiLeaks.

In a stream of tweets, the Republican presidential nominee urged Americans to examine Alicia Machado's personal history and her "sex tape".

He implied his Democratic rival Hillary Clinton had secured US citizenship for Venezuelan-born Ms Machado.

In response, Mrs Clinton tweeted: "This is unhinged, even for Trump."

Mr Trump said he did not discuss who would pay for the wall.

He also called Mexicans "amazing" and "spectacular" people, in contrast to earlier comments branding Mexican migrants "rapists" and "murderers".

Mr Pena Nieto said Mexicans had been hurt but he respected that Mr Trump genuinely wanted to build relations.

Mr Trump will later fly to Phoenix, Arizona, to deliver a key speech on measures to tackle illegal immigration.

The Republican has seen his poll ratings slip since the party conventions last month.

The Vermont senator and former Democratic presidential candidate appeared with Mrs Clinton at a campaign event in New Hampshire.

Mrs Clinton and Mr Sanders have been negotiating since she all but guaranteed the nomination in June.

Mr Sanders hopes to have a large influence on the Democratic platform.

"She will be the Democratic nominee for president and I intend to do everything I can to make certain she will be the next president of the United States," he said.
