US Senator Elizabeth Warren has revealed that a DNA test shows “strong evidence” that she has distant Native American ancestry.
She took the test after President Donald Trump taunted her in speeches, calling her a “fake Pocahontas” and challenging her to take the test.
The DNA test suggests Ms Warren has a Native American ancestor dating back six to 10 generations.
Many believe the Democrat is preparing for a presidential bid in 2020.
What exactly was revealed?
Ms Warren, who is up for re-election in Massachusetts, shared the report along with a video of family and colleagues discussing her heritage on Monday.
The DNA report was conducted by geneticist Carlos Bustamante of Stanford.
“The vast majority” of Ms Warren’s ancestry is European, it concludes, but “the results strongly support” a Native American ancestor.
This puts Ms Warren as between 1/32 and 1/512 Native-American, according to the Boston Globe.
Ms Warren herself is not a part of any native tribe. While the results of the test do confirm there is native heritage in Ms Warren’s family tree, critics could still point out how imprecise these DNA tests can be.
The senator’s accompanying video begins with a clip of the president mocking her at a rally, saying: “She said she’s Native-American and I said, Pocahontas!”
Pocahontas was the daughter of a 17th Century indigenous chief.
The video shows Ms Warren’s family – including brothers who say they are Republicans – criticising the president’s taunts.
A cousin who is identified as being a member of the Cherokee Nation adds: “It’s offensive to me, not just as Betsy’s cousin, but as a Native-American.”
How has Warren been taunted?
Ms Warren has denied benefitting from her background since 2012, when it emerged that she was listed as a minority in a Harvard Law School directory.
She has frequently faced attacks from the White House and Republicans over whether she used claims of native ancestry to advance her career.
At a rally in Montana this summer, the president said he would give $1m (£761,000) to charity if Ms Warren would prove her claims of Native-American heritage.
In 2012, two Republican aides were recorded making offensive gestures linked to Native Americans while poking fun at then-candidate Ms Warren.
Asked about the DNA test, Kellyanne Conway, White House counsellor, told reporters: “Everybody likes to pick their junk science and sound science depending on the conclusion.”
One clip in the new video shows White House Press Secretary Sarah Sanders saying: “What most people find offensive is Senator Warren lying about her heritage to advance her career.”
In response, the video has a number of Ms Warren’s colleagues and employers affirm that her background paid no role in her hiring.
Her campaign has also shared a number of documents and testimonials stating Ms Warren’s ancestry did not impact upon her career.
In the video, Ms Warren says her critics attack her as an insult or “to distract from the kinds of changes I’m fighting for”.
“Trump can say whatever he wants about me, but mocking Native Americans or any group in order to get at me?” she asks. “That’s not what America stands for.”
How does this echo Trump attacks on Obama?
The hubbub around Ms Warren’s ancestry recalls the attacks President Barack Obama faced over his background.
During Mr Obama’s campaign, Mr Trump called repeatedly for him to release his birth certificate to prove he was born in America.
The rumours that Mr Obama was a foreigner persisted throughout his presidency and, in 2011, the White House released his birth certificate to quash the controversy.
