Donald Trump owed chance to lead, says Hillary Clinton in concession speech
Hillary Clinton has said the United States proved to be "more divided than we thought" but urged supporters to give Donald Trump "a chance to lead".
Standing before a crowd of crestfallen campaign aides and backers, Mrs Clinton said: "This is painful and it will be for a long time."
Mr Trump's triumph, declared only after midnight, will end eight years of Democratic dominance of the White House.
He will govern with Republicans controlling both houses of Congress and lead a country deeply divided by his rancorous campaign against Mrs Clinton.
He faces fractures within his own party, too, given the numerous Republicans who refused to back him or only tepidly supported his nomination.
As he claimed victory early on Wednesday, Mr Trump urged Americans to "come together as one united people".
That sentiment was echoed by Republican House Speaker Paul Ryan, who had been a reluctant Trump supporter.
"This needs to be a time of redemption, not a time of recrimination," Mr Ryan said in a news conference, saying Mr Trump had earned a "mandate" to enact his agenda.
Mrs Clinton, hoping to become the first woman to be elected president, conceded defeat in a telephone call to Mr Trump.
With several million votes still to be counted, she held a narrow lead in the nationwide popular vote. Most of the outstanding votes appeared to be in Democratic-leaning states, with the biggest chunk in California, a state Mrs Clinton overwhelmingly won.
With almost 125 million votes counted, The Associated Press tally had Mrs Clinton with 47.7% and Mr Trump with 47.5%.
Summoning her most magnanimous tone after a bitter race, Mrs Clinton said of the man whose victory she declared would be a danger to America and the world: "I hope that he will be a successful president for all Americans."
As her supporters waited for her in a New York ballroom, the scene of despair played out for all on live television. Cameras zoomed in on the exhausted and miserable faces of several of her closest aides, some dressed in hoodies or other casual clothing. The familiar campaign music of Bruce Springsteen in the background added to the sense of disappointment.
"We have seen that our nation is more deeply divided than we thought," Mrs Clinton said in a speech she never hoped to deliver. "But I still believe in America and I always will."
Global stock markets and US stock futures plunged early on Wednesday, but later recovered. The Dow Jones industrial average was up almost 1% in midday trading in New York.
President Barack Obama congratulated Mr Trump in a phone call and invited him to a meeting at the White House on Thursday to discuss transition.
Mr Obama said at the White House that he had significant differences with Mr Trump but added that the same had been true when he took office after George W Bush. He said Mrs Clinton had accomplished much as the first woman nominated for president by a major political party.
He noted that despite the painful loss for the Democrats, "the sun came up" as usual on Wednesday morning.
Mr Trump campaign manager Kellyanne Conway said Mr Obama and Mr Trump had "a very nice talk" when the president called him.
Mr Trump, who spent much of the campaign urging supporters on as they chanted "lock her up", said the nation owed Mrs Clinton "a major debt of gratitude" for her years of public service.
A New York real estate developer who lives in a sparkling Manhattan high-rise, Mr Trump forged a connection with white, working class Americans who feel left behind in a changing economy and diversifying country.
He cast immigration, both from Latin America and the Middle East, as the root of problems plaguing many Americans and tapped into fears of terrorism emanating at home and abroad.
Republican Senate candidates fended off Democratic challengers in key states, including North Carolina, Indiana and Wisconsin. Republicans also maintained their grip on the House.
Senate control means Mr Trump will have great leeway in appointing Supreme Court justices, which could shift the bench to the right for decades.
Mr Trump has pledged to usher in sweeping changes to US foreign policy, including building a wall along the US-Mexico border and suspending immigration from countries with terrorism ties.
He has praised Russian President Vladimir Putin and spoken of building a better relationship with Moscow, worrying some in his own party who fear he will go easy on Mr Putin's provocations.
Mr Putin sent him a telegram of congratulations.
Upending years of political convention on his way to the White House, Mr Trump levelled personal insults against his rivals, declared Mexican immigrants rapists and murderers, and vowed to suspend Muslim immigration to the US.
He never released his tax returns, breaking with decades of campaign tradition, and eschewed the kind of robust data and field efforts that helped Mr Obama win two White House terms, relying instead on large, free-wheeling rallies to energise supporters. His campaign was often in chaos.
Mrs Clinton faced persistent questions about her honesty and trustworthiness. And her troubles flared anew late in the race, when the FBI director reviewed new emails from her tenure at the State Department. Just two days before election day, Mr Comey said there was nothing in the material to warrant criminal charges against Mrs Clinton.
Mr Trump will inherit a nation deeply divided by economic and educational opportunities, race and culture.
Women nationwide supported Mrs Clinton by a double-digit margin, while men significantly backed Mr Trump. More than half of white voters went for the Republican, while nearly nine in 10 blacks and two-thirds of Hispanics voted for the Democrat.
