US presidential hopeful Donald Trump has been repeatedly criticised for making lewd, racist, sexist, xenophobic, Islamophobic, and otherwise hateful comments during his presidential campaign.

When Trump first proposed the idea of building a wall along America's southern border, he said: "I will build a great wall. Nobody builds walls better than me, believe me."

Trump's border wall was slammed as "just fantasy" by Clinton, who was also quick to mock the business tycoon's claims of a "winning" temperament.

The former reality TV star has apologised for some of the "foolish things" he's said, but has mainly defended himself, saying he is more level-headed than his election rival Hillary Clinton.

Here's a montage of some of Trump's most outrageous comments.
