Donald Trump

According to Melania Trump, the story of her American arrival is quite simple: "I came to the United States, to New York, in 1996," she told CNN's Anderson Cooper on February 29, 2016.

But Melania posed for those photos, which appeared in the French magazine Max, during a shoot in New York City in 1995 when she was 25 and known as "Melania K," according to Bojan Pozar, the author of the biography "Melania Trump: The Inside Story."

That year is possibly the key to whether or not Melania, now 46, broke immigration law by working in the US without the proper visa.

Mr Trump shocked party members on Tuesday when he refused to endorse Mr Ryan and Senator John McCain in their campaigns for re-election in November.

Mr Ryan, the party's highest-ranking elected official, had himself long delayed endorsing Mr Trump.

"I support and endorse our Speaker... Paul Ryan," Mr Trump said on Friday.

"We need unity - we have to win this election," Mr Trump said during a campaign stop in Green Bay, Wisconsin - Mr Ryan's home state.

While they might "disagree on a couple of things", they agreed on a lot as well, he added.

But for all his talk of terrorism, Russia and other geopolitical challenges, the underlying argument he wanted to make was clear: it's a serious business being commander-in-chief and the Republican who wants his job isn't fit for the Oval Office.

Obama ridiculed Donald Trump's recent suggestion that the election system could be rigged, called on the candidate to act like a president since he's soon to be briefed on confidential information and implied that he didn't believe the billionaire businessman could be trusted with America's nuclear codes.

"The campaign is in very good shape. We are organised. We are moving forward," Paul Manafort told Fox News.

US media outlets reported the campaign was in turmoil after Mr Trump repeatedly attacked the parents of a fallen US solider.

Staffers told CNN that they "feel like they are wasting their time".

However, Mr Manafort blamed those reports on Mr Trump's opponent Democrat Hillary Clinton.

"He's been weak, he's been ineffective," Republican candidate Mr Trump said of Mr Obama in a Fox News interview on Tuesday.

Mr Obama has questioned why Mr Trump's party hasn't disowned him.

Mr Trump has also turned on two senior figures in his own party who have publicly criticised him.

"There has to come a point at which you say: 'Enough'," Mr Obama said.

Mr Trump has been sharply criticised for attacking the parents of a fallen US soldier who spoke out against him.

He has also been condemned for backing the Russian annexation of Crimea.

Mr Obama said he had had policy differences with previous Republican presidents and candidates - but added that he had never thought they could not function as president.

He told a rally in Columbus, Ohio, that he had heard "more and more" that the contest would be unfair. He offered no immediate evidence.

At another event he called Democratic rival Hillary Clinton "the devil".

Mr Trump has come under fire from across the political divide for remarks he made about the parents of a US Muslim soldier killed in action.

On the forthcoming vote, he told supporters "I'm afraid the election is going to be rigged, I have to be honest".

 The standalone clip, entitled 3am, has been posted on YouTube.

Republican candidate Donald Trump is seen with a copy of a book called Great Speeches by A. Hitler in the video.

When Homer signals that he might vote for Trump, Marge says: "If that's your vote, I question whether I can ever be with you again."

Homer replies: "And that's how I became a Democrat."

Clinton and Trump are set to face each other in the US presidential election, which takes place on 8 November.

Speaking at a rally in a high school gym in Pennsylvania, Mr Trump attacked Bernie Sanders for capitulating to Mrs Clinton in the Democratic race.

"He made a deal with the devil," the tycoon said. "She's the devil."

Democrats and Republicans alike have condemned Mr Trump for his remarks about a US Muslim soldier's parents.

Showing a characteristic refusal to back down from a fight, Trump took the almost unthinkable step of publicly escalating a feud with the parents of fallen US solider, Capt. Humayun Khan, who blasted Trump at last week's Democratic convention as unfit for the presidency.

And in an interview with ABC's George Stephanopoulos, Trump said Russian President Vladimir Putin wouldn't make a military move into Ukraine -- even though Putin has already done that by seizing the Crimean Peninsula in 2014.
