Donald Trump

 "Hillary wants to abolish -- essentially abolish the Second Amendment. By the way, if she gets to pick, if she gets to pick her judges, nothing you can do, folks. Although the Second Amendment people, maybe there is, I don't know," Trump said.

He added: "But I tell you what, that will be a horrible day, if Hillary gets to put her judges in, right now we're tied."

Trump's ambiguous comments alarmed some political observers as to whether he was threatening her life or calling for increased political activity.

Michael Sandford was arrested at a Trump rally in Las Vegas in June after he allegedly tried to grab a police officer's gun.

The 20-year-old told investigators he wanted "to kill Trump." He faces up to a decade in jail if convicted.

Back home in England, Sandford's mother Lynne says she's worried the 20-year-old is not coping in custody.

Critics, including opponent Donald Trump, are slamming former Secretary of State Hillary Clinton for having received emails mentioning him on her controversial personal email server.

Trump took to Twitter on Monday to link Clinton to Shahram Amiri's death, writing, "Many people are saying that the Iranians killed the scientist who helped the U.S. because of Hillary Clinton's hacked emails."

The group - which includes the former CIA director Michael Hayden - said Mr Trump "lacks the character, values and experience" to be president.

Many of the signatories had declined to sign a similar note in March.

"None of us will vote for Donald Trump," the letter states.

The letter comes after a number of high-profile Republicans stepped forward to disown Mr Trump.

Mr Trump has broken with years of Republican foreign policy on a number of occasions.

Mr McMullin, the former chief policy director of the House Republican Conference, is expected to formally file his candidacy on Monday.

He is likely to face challenges on ballot deadlines and fundraising just three months before Election Day.

The 40-year-old Mormon has never held elected office.

Mr McMullin, an outspoken critic of the Republican nominee, Donald Trump, released a statement to ABC News.

The satire GoFundMe page was started in response to the US Republican candidate's remarks at his rally in Virginia, where he appeared flippant about handling the medal - a military honour awarded to combat-wounded servicemen and women.

Mr Trump stood on stage holding a Purple Heart medal that was handed to him by a veteran moments earlier.

George P. Bush, the Texas land commissioner, is breaking with his father, a former Donald Trump Republican primary rival, to back the GOP nominee. George P. Bush's move comes after a nasty Republican primary battle in which Trump repeatedly mocked Jeb Bush, a former Florida governor, as "low energy," among other insults.

It's one more historic barrier President Barack Obama has shattered.

His vehement warnings that GOP nominee Donald Trump is temperamentally and intellectually unfit for the Oval Office leave Obama standing apart from almost all of his 43 predecessors in the extent to which he has publicly expressed a hostile attitude to a potential successor.

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.
