U.S. Republican presidential candidate Donald Trump on Thursday promised to do more for the African-Americans than his rival Democratic presidential candidate Hillary Clinton could do in her lifetime.

Trump, at the third and final presidential debate with Clinton broadcast live early Thursday, claimed that Clinton and President Barack Obama had not made much impact on them.

“Our inner cities are a disaster. You get shot walking to the store. They have no education. They have no jobs. I will do more for African-Americans and Latinos than she can ever do in 10 lifetimes.”

“All she has done is talk to the African-Americans and to the Latinos. After they get your votes and then they come to say we’ll see you in four years."

Trump, however, stressed that his administration would not take care of illegal immigrants or their debts.

He cautioned against voting for Clinton, saying a vote for her is a vote for the continuation of Obama’s administration.

He claimed that America "have been depleted militarily" adding, “our policemen and women are disrespected; we need law and order but we need justice too”.

“We’re going to make America strong again. We’ll make America great again, and it has to start now.

“We cannot take four more years of Barack Obama and that is what you get when you get her,” he said.

In her remarks at the debate, Clinton pledged to reach out to all Americans irrespective of their affiliations.

“I would like to say to everyone watching that I’m reaching out to all Americans, Democrats, Republicans and independents because we need everyone to help make our country what it should be.

“I know that we have the awesome responsibility of protecting our country and incredible opportunity of working to try to make life better for all of you,” she said.

According to her, she has made the cause of children and families the centre of mission of her life’s work adding, “that’s what my mission will be in the presidency”.

“I will stand up for families against powerful interests, against corporations, I will do everything I can to make sure you have good jobs with rising income,” she said.

The Democratic candidate also pledged to ensure that America children had better education.

The News Agency of Nigeria (NAN) reports that Trump had during the debate, pledged to cut taxes and focus on growing the economy.

Clinton, however, disagreed with Trump, saying that “we need to put more money in social security trust fund”.

“We will make sure we have sufficient resources and that will mean raising the cap… I want to raise health benefits for women.

“If Trump repeals the America healthcare, healthcare will get worse…,” she said.

NAN reports that 52 per cent of American voters remain unchanged in their position that suggest that Clinton was ahead of Trump by nine per cent before the final debate, according to Reuters’s poll.
