Donald Trump pledges to reject bigotry if elected president

Republican presidential candidate Donald Trump has said that he will reject bigotry, hatred and oppression in all its forms if elected president, a day after he proposed an extreme vetting process for those coming to the US.

"This is my pledge to the American people: as your President I will be your greatest champion. I will fight to ensure that every American is treated equally, protected equally, and honoured equally," he said in a Facebook post.

"We will reject bigotry and hatred and oppression in all its forms, and seek a new future built on our common culture and values as one American people," Trump said.

His comments came a day after he proposed an extreme vetting process for those coming to the US.

"Just as we won the Cold War, in part, by exposing the evils of communism and the virtues of free markets, so too must we take on the ideology of radical Islam," he said in another post.

"While my opponent accepted millions of dollars in foundation donations from countries where being gay is an offense punishable by prison or death, my administration will speak out against the oppression of women, gays and people of different beliefs," Trump said.
