Pennsylvania is high on Friday’s agenda. Hillary Clinton’s first stop is Pittsburgh, Donald Trump is due later in Hershey – a day after Melania Trump spoke in the state.

Clinton will then head on to Detroit, Michigan, where boosting the black vote is seen as key for the Democrats.

Trump’s first stop, however, is Atkinson in New Hampshire, where polls published on Thursday suggest Trump has closed the gap with Clinton – or even edged ahead.

BBC Newsround, external has been going around America asking people that are too young to vote to explain the 2016 election.

Watch their full piece to hear what the youth of America thinks about their next president, who hopefully won't be a puppet.

Barack Obama won over the crowd at the start of his second campaign rally of the day in Florida by imitating a bird of prey.

It's a tradition at the University of North Florida in Jacksonville to perform a "swoop" to show support for the university's sports teams, known as the Ospreys. 

The President took a few steps back from the podium, raised a leg and made a flapping motion with his arms. 

It seemed to do the trick with the audience, although they were already going wild before his ornithological exertions. 

He went on to attack Donald Trump as someone who would "do damage to our democracy" and tell the crowd of Hillary Clinton supporters they have "five days to decide the future of America". 

Florida is one of the states that has already started voting.

Clinton referred to the 1973 Justice Department lawsuit, external that accused Trump of refusing to rent apartments to minorities to his potential presidency. 

"If he doesn't respect all Americans, how can we trust him to serve all Americans?"

She then calls out Trump for his comments on the Central Park Five, or five teens who were wrongfully convicted in a 1989 New York City rape. 

Trump has insisted the men are guilty.

"Do we want this man appointing judges?" Clinton asked. The crowd shouts "No!"

"Do we want him controlling the Justice Department?" she continued. The crowd repeats "No!"

But what kind of change will that be, Clinton asked the crowd, contrasting her vision for a hopeful future with her rival Trump's fear-mongering version. 

She then invokes First Lady Michelle Obama: "The president doesn't change who you are, it reveals who you are.

"And we've all seen all we need of Donald Trump."

Clinton then made fun of Trump boasting about his temperament at a rally earlier in the day.

Fox News Business reports that Trump has told his aides that he wants to appoint his campaign finance chair, Steve Mnuchin, to be secretary of treasury after he is elected.

Mnuchin, a former partner at Goldman Sachs, founded the hedge fund company Dune Capital Management LP.

Several eagle-eyed Twitter users have pointed out that Donald Trump appears to be wearing glasses in the photograph his campaign team shared of him watching his wife's speech. 

But while he doesn't usually sport specs, we have seen him wearing them in the past - including when he read a poem called The Snake at a rally in Iowa at the beginning of the year.

At a rally in Greenville, North Carolina, Clinton talks about how anxious she was before the Chicago Cubs' historic win on Wednesday. 

She then alluded to making more history next week on election day. 

Clinton added the last time the Cubs won the World Series, women couldn't vote. 

"I think women are making up for that in this election," she said.

The eldest daughter of Donald Trump has appeared for the first time in New Hampshire to support her dad.

The popular businesswoman said few issues are unique to women: "Women's issues are jobs, women's issues are security, women's issues are the major issues affecting this country."

Meanwhile, Ivanka Trump has become a popular model for women seeking to alter their appearance, a Houston surgeon tells ABC's Nightline programme.

No word yet on anyone seeking to look more like The Donald himself.

New York-based novelist Paul Auster is despairing over the US election.

"Most people I know are on the verge of a nervous breakdown," he tells BBC Newsnight’s Emily Maitlis.

"There are times when Trump does sound like Hitler. The 'International Banking Conspiracy' is just a code word for Jews. It's very scary. Plus his embrace by the white supremacist right wing. There were 60 of these groups 10 years ago. Now there are 900. Trump has enabled them."

Once Trump's arch-enemy in the primaries, Texas Senator Ted Cruz now stands next to Trump's running mate Mike Pence on the tarmac in Iowa before boarding the Trump-Pence aircraft to head to Michigan.

Under a barrage of questions from reporters, Cruz said he voted for Trump on Monday.

"I'm doing everything I can to defeat Hillary Clinton. She would be an absolute disaster as president."

No issue is more important than the US Supreme Court, he added, and it's imperative to keep the Republican majority in the Senate.

What's at stake in Supreme Court?

It wasn't so long ago that Cruz and Trump were hurling insults at each other, like "rat", "pathological liar" and "coward".

The insults between Trump and Cruz

"We must win on November 8th. And we must come together as Americans. We must treat each other with respect and kindness even when we disagree. I will be there to support my husband's efforts to support all Americans when he is president.

"Donald Trump will make America fair. He will make America safe. He will make America prosperous. He will make America proud."  

She finishes her remarks by promising her husband will "make America great again".

She walks off stage to the sound of Living in America by James Brown.

"Our culture has gotten too mean and too rough, especially for children and teenagers," says Melania Trump about childhood bullying and online trolling.

"We have to find a better way to talk to each other to disagree with each other, to respect each other." 

She says that anti-bullying efforts will be one of her issues if she is to become first lady.

It's "absolutely unacceptable", she adds, when children are mocked, bullied and attacked online anonymously.

To some, her remarks seemed at odds with her husband's long history of using Twitter to insult people.

"It will be my honour and privilege to serve this country. I will be an advocate for women and for children.

"I'm a full-time mother to our (10-year-old) son Barron, an incredible boy."

She talks about her experience discussing politics with her young son, and how she wants him to know how lucky he is to be born an American.

"I want my little boy to know that he is blessed to have been born in a country that values individual freedom."

"Donald knew he could not sit by anymore and watch what is happening in this country," she says as the crowd begins to chant "Trump".

"What kind of country do we want? Do we want a country that is safe with secure borders? Yes? Do we want a country where everyone gets a fair shot?" 

"Yes!" the crowd howls in response.

"Do we want a country that honours our constitution?" she continues in the call-and-response format.
