WASHINGTON --Donald Trump claimed his place Wednesday as America's 45th president, an astonishing victory for the celebrity businessman and political novice who capitalized on voters' economic anxieties, took advantage of racial tensions and overcame a string of sexual assault allegations on his way to the White House.
Trump's triumph over Hillary Clinton, not declared until well after midnight, will end eight years of Democratic dominance of the White House. He'll govern with Congress fully under Republican control and lead a country deeply divided by his rancorous campaign against Clinton. He faces fractures within his own party, too, given the numerous Republicans who either tepidly supported his nomination or never backed him at all.
As he claimed victory, Trump urged Americans to "come together as one united people."
WATCH PRESIDENT-ELECT DONALD TRUMP'S FULL VICTORY SPEECH
Clinton, who hoped to become the nation's first female president, called her Republican rival to concede but did not plan to speak publicly until Wednesday morning.
President Barack Obama invited Trump to meet with him at the White House on Thursday to discuss transition, and the White House said the president planned to address the election results in a statement Wednesday. White House spokesman Josh Earnest said Obama called Trump to congratulate him and also called Clinton to convey his admiration for the "strong campaign she waged throughout the country."
The White House said Obama's televised statement Wednesday would focus on "what steps we can take as a country to come together after this hard-fought election season."
Trump, who spent much of the campaign urging his supporters on as they chanted "lock her up," said the nation owed Clinton "a major debt of gratitude" for her years of public service. Trump campaign manager Kellyanne Conway said Obama and Trump had "a very nice talk" when the president called to congratulate him in the early hours Wednesday.
The Republican blasted through Democrats' longstanding firewall, carrying Pennsylvania and Wisconsin, states that hadn't voted for a GOP presidential candidate since the 1980s. He needed to win nearly all of the competitive battleground states, and he did just that, including Florida, Ohio, North Carolina and others.
Global stock markets and U.S. stock futures plunged, but later recovered somewhat, reflecting investor concern over what a Trump presidency might mean.
A New York real estate developer who lives in a sparkling Manhattan high-rise, Trump forged a striking 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 the problems plaguing many Americans and tapped into fears of terrorism emanating at home and abroad.
GOP 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 Trump will have great leeway in appointing Supreme Court justices, which could mean a shift to the right that would last for decades.
Trump has pledged to usher in sweeping changes to U.S. foreign policy, including building a wall along the U.S.-Mexico border and suspending immigration from countries with terrorism ties. He's also praised Russian President Vladimir Putin and spoken of building a better relationship with Moscow, worrying some in his own party who fear he'll go easy on Putin's provocations.
Putin sent him a telegram of congratulations early Wednesday.
WATCH: DONALD TRUMP'S ROAD TO THE WHITE HOUSE
Trump upended years of political convention on his way to the White House, leveling harshly personal insults against his rivals, deeming Mexican immigrants rapists and murderers, and vowing to temporarily suspend Muslim immigration to the U.S. He never released his tax returns, breaking with decades of campaign tradition, and eschewed the kind of robust data and field efforts that helped Obama win two terms in the White House, relying instead on his large, free-wheeling rallies to energize supporters. His campaign was frequently in chaos, and he cycled through three campaign managers.
Conway, his final campaign manager, touted the team's accomplishments as the final results rolled in, writing on Twitter that "rally crowds matter" and "we expanded the map."
Clinton spent months warning voters that Trump was unfit and unqualified to be president. But the former senator and secretary of state struggled to articulate a clear rationale for her own candidacy.
She faced persistent questions about her honesty and trustworthiness. Those troubles flared anew late in the race, when FBI Director James Comey announced a review of new emails from her tenure at the State Department. On Sunday, just two days before Election Day, Comey said there was nothing in the material to warrant criminal charges against Clinton.
Trump will inherit an anxious nation, deeply divided by economic and educational opportunities, race and culture.
Exit polls underscored the fractures: Women nationwide supported Clinton by a double-digit margin, while men were significantly more likely to back Trump. More than half of white voters backed the Republican, while nearly 9 in 10 blacks and two-thirds of Hispanics voted for the Democrat.
Doug Ratliff, a 67-year-old businessman from Richlands, Virginia, said Trump's election was one of the happiest days of his life.
"This county has had no hope," said Ratliff, who owns strip malls in an area badly beaten by the collapse of the coal industry. "Things will change. I know he's not going to be perfect. But he's got a heart. And he gives people hope."
The Republican Party's tortured relationship with its nominee was evident right to the end. Former President George W. Bush and wife Laura Bush declined to back Trump, instead selecting "none of the above" when they voted for president, according to spokesman Freddy Ford.
House Speaker Paul Ryan, a reluctant Trump supporter, called the businessman earlier in the evening to congratulate him, according to a Ryan spokeswoman. Senate Majority Leader Mitch McConnell said the American people "have chosen a new direction for our nation."
