Republican Presidential nominee Donald Trump ended five years of uncertainty over his views by declaring Friday that U.S. President Barack Obama "was born in the United States, period."
The Republican nominee in 2011 was a force behind a movement arguing, without evidence, that Obama was born abroad. Since then, he has refused to directly say what he believes, until he ended the ambiguity Friday.
In a campaign appearance Friday, Trump again blamed Clinton for starting the controversy, during the 2008 election when she was running against Obama. Numerous news media outlets have investigated the allegation and found there is no evidence to support it.
Clinton, also in Washington Friday, dismissed Trump’s efforts to raise questions about the president’s birthplace.
Speaking before The Black Women’s Agenda Symposium on her second day of campaigning since falling ill during a September 11 commemoration ceremony, Clinton said, “For five years, he has led the birther movement to delegitimize our first black president. His campaign was founded on this outrageous lie."
“He is feeding into the worst impulses, the bigotry and bias that lurks in our country. Barack Obama was born in America, plain and simple, and Donald Trump owes him and the American people an apology,” Clinton added.

Trump's appearance Friday occurred just a few blocks from the White House, at his new luxury Trump International Hotel, where he paid tribute to several Medal of Honor recipients.
After Trump’s campaign event, Clinton’s campaign manager Robby Mook issued a statement describing Trump’s actions Friday as “disgraceful.”
“After five years of pushing a racist conspiracy theory into the mainstream, it was appalling to watch Trump appoint himself the judge of whether the President of the United States is American. This sickening display shows more than ever why Donald Trump is totally unfit be president.”
President Obama addressed the issue Friday, telling reporters at the White House he will not comment on the matter anymore. “We got other business to attend to. I was pretty confident where I was born. I think other people were as well, and my hope would be that the presidential election reflects more serious issues than that.”

In an attempt to put an end to the controversy, Obama produced his birth certificate in 2011. It showed he was born at the Kapiolani Medical Center in Hawaii on August 4, 1961.
Shortly after making his birth certificate public, Obama ridiculed Trump at the annual White House Correspondents' Dinner, at which Trump was a guest.
"No one is prouder to put this birth certificate matter to rest than The Donald,” Obama said. And that's because he can finally get back to focusing on the issues that matter, like, did we fake the moon landing? What really happened in Roswell? And where are Biggie and Tupac?"
Trump’s unfounded claims since 2011 helped launch his political career, as it further raised his national profile and endeared him to citizens on the far right.
But as the race for the White House tightened, the issue became a liability for Trump among African American, Latino and moderate voters who are needed to win the presidential election.
Latest polls
The birther saga continues to make waves as the latest opinion polls show the two presidential candidates locked into what amounts to a statistical tie at a time when third party candidates could alter the race.
The latest New York Times/CBS News Poll shows Clinton ahead of Trump by a slim 46 percent to 44 percent margin among likely voters nationwide. The RealClear Politics national average shows Clinton clinging to a narrow 45.7 to 44.2 lead.
The Clinton campaign is trying to regain Clinton’s lead over Trump by making a concerted effort to win over disillusioned voters who are leaning toward Libertarian Party candidate and former New Mexico Governor Gary Johnson and Green Party nominee Jill Stein.
These voters, many of whom are millennials, live in states that have fallen on hard economic times due primarily to a dramatic decline in the manufacturing sector.
Clinton hopes to get a boost among these voters on Saturday when Senators Bernie Sanders and Elizabeth Warren, two politicians young liberal voters are loyal to, hit the campaign trail on her behalf. The senators will campaign in the battleground state of Ohio, where Clinton and Trump are tied in the polls.
After leaving Washington, Trump will turn his attention to the southeastern state of Florida, where recent polls show him increasing his lead over Clinton, with a Friday evening rally in Miami and another one Sunday in Fort Myers.
