US President Donald Trump has mocked democratic senator and presidential candidate Elizabeth Warren on Twitter for her claim that she is of Native American heritage.
Trump posted a video on Monday which featured a clip from a live stream on Warren's Instagram page along with a caption labelling her "Pocahontas".
"If Elizabeth Warren, often referred to by me as Pocahontas, did this commercial from Bighorn or Wounded Knee instead of her kitchen, with her husband dressed in full Indian garb, it would have been a smash," the Tweet reads".
"Wounded Knee" refers to an 1890 massacre in which approximately 150 Native Americans were killed.
The video shows the former Harvard law professor in her kitchen on New Year's Eve, drinking a beer and introducing her husband as "her sweetie".

On the day the live stream was posted, Warren had announced that she would be running for US President in 2020 - the first major candidate to do so.
The video was first posted shortly after 1pm, garnering more than 9,000 responses, before being deleted and replaced with an almost identical post almost an hour later.
The second post had an additional comma, making it grammatically correct.
In another Tweet, the President further mocked the live stream, which he called a "beer catastrophe":
"Best line in the Elizabeth Warren beer catastrophe is, to her husband, “Thank you for being here. I’m glad you’re here” It’s their house, he’s supposed to be there!"
Twitter users were quick to call out the President for racism and demand the Tweet be removed.
"Your racist tweet is a disgrace, and it dishonours the high office you hold," Tweeted one user.
"It dishonours the entire country. Disgraceful," wrote another.
The feud between Trump and Warren goes back to the 2016 presidential campaign after Trump seized on Warren's claims that she had Native American heritage, labelling her "Pocahontas".
At a campaign rally in July last year, Trump said he would donate a million dollars to Warren's "favourite charity" if she took a test proving her Native American heritage.
Warren then hit back by publishing the results of a DNA test confirming her ancestry.
The test, performed by Stanford University professor Carlos Bustamante, concluded that while the vast majority of Warren's ancestry is European, there is definitive evidence that she has Native American blood.
