Clinton attacks Trump in new ad over black vote

Democrat Hillary Clinton called on Friday for voters to reject the "bigotry" of Donald Trump's White House campaign, releasing a television ad criticizing his efforts to appeal to black voters and saying she was reaching out to people from all parties who are troubled by his candidacy.

The ad shows video of Trump's controversial pitch to black voters, in which the Republican candidate urges them to support him by asking, "What do you have to lose?" It also shows headlines about a racial discrimination lawsuit the New York real estate mogul faced in the 1970s.

Clinton's presidential campaign said the ad, released a day after she gave a speech accusing Trump of fueling America's "radical fringe," would air in the hotly contested states of Florida, North Carolina, Ohio and Pennsylvania.

Polls give Clinton a wide margin over Trump among Hispanic voters, but he is on a pitch to reduce her advantage by stressing he would create jobs for all.

Trump pressed on with trying to broaden his appeal to minority voters on Friday, as he met with Hispanic business leaders at his signature hotel in Las Vegas.

Clinton attacks came during a difficult week for her campaign, as the release of new emails from her time as secretary of state revived criticism of her decision to use a private address and server rather than a government one.

The emails also stoked scrutiny of her family's charitable foundation, including accusations that major corporate and foreign donors gave money in hopes of securing more access to then-Secretary Clinton. Her campaign says no donors received any special favors.

Meanwhile, the doctor who declared Donald Trump would be "unequivocally the healthiest individual ever elected to the presidency" says he wrote his letter in just five minutes. He said the letter was written while a limousine sat outside his office waiting for it.

The Republican nominee famously produced a note from Dr Harold Bornstein, his physician for 35 years, declaring him as having an excellent bill of health in December. 

But Dr Bornstein stands by his assessment, telling NBC News: "His health is excellent, especially his mental health", adding that his brain is switched on "24 hours a day".
