Jacinda Ardern denounces Donald Trump's comments about Democrat congresswomen

Prime Minister Jacinda Ardern has spoken out against Donald Trump after he posted "racist" tweets aimed at Democratic congresswomen.

On Monday Trump posted on Twitter saying four American congresswomen should "go back" to the countries they "originally came from".

He said the women "originally came from countries whose governments are a complete and total catastrophe."

On Tuesday Primer Minister Jacinda Ardern condemned these comments, telling RNZ she "completely and utterly disagrees with him."

"We should celebrate our diversity, we do in New Zealand, I'm proud of that and so I obviously take a very different view to President Trump," she told RNZ.

The women in question are understood to be Alexandria Ocasio-Cortez, Ilhan Omar, Rashida Tlaib and Ayanna Pressley. 

All of the women except for Omar were born in the US.

Trump's comments have been condemned by Speaker of the House Nancy Pelosi as "xenophobic."

"When [Donald Trump] tells four American congresswomen to go back to their countries he reaffirms his plan to 'Make America Great Again' has always been about making America white again," she Tweeted on Monday.

Democratic frontrunner Bernie Sanders called Trump a "racist", and Texas congressman Joaquin Castro wrote "They're Americans. You're a bigot."

Trump has since defended his comments about the women, saying at an event on Tuesday that he doesn't care if people think his Tweets are racist because "many people agree with me."

He also hinted at the four women "hating America."

"As far as I'm concerned, if you hate our country, if you're not happy here, you can leave," he said at the White House event on Monday.
