However, a recent exhaustive review of documents and interviews with Warren's former colleagues by The Boston Globe found no evidence that her claims of Native American heritage were ever considered by those involved in the hiring process.
President Donald Trump on Tuesday morning called Senator Elizabeth Warren, D-Mass., a "complete and total Fraud", opening a second day of sparring between the current White House occupant and a likely 2020 challenger over her Native American heritage.
While the results indicated Warren may indeed have a trace of Native American heritage - anywhere from 1/64 to 1/1,024 - many Republicans and pundits mocked her for a political miscalculation.
"She only claimed it when she was in her late 30s and beginning to climb the law professor ladder from the University of Texas to Harvard", he explained.
Trump called on Warren to apologize.

When running for her position in the senate during 2013, she was accused by opposition candidate Scott Brown of fabricating her claims to get ahead in her career.
"Pocahontas (the bad version), sometimes referred to as Elizabeth Warren, is getting slammed", Trump said in one of his tweets.
In releasing the results, Warren referred back to a promise Trump made in July when he offered to donate $1 million to her favourite charity if a DNA test proved her Native American bloodline. "Flashbacks" revealed Warren claiming direct knowledge of a Cherokee ancestor (and alleging that her family experienced racism as a result), and the official Cherokee Nation issued a stinging rebuke against the MA senator Monday night, reminding her that the Nation has strict guidelines for membership, which she does not meet. These and other fabulations - and Warren's defensive doubling-down when they were reported - became an issue in her US Senate race in 2012.
But Warren now has documentation to back up her family lore - an analysis of her genetic data performed by Carlos Bustamante, a professor of genetics at Stanford and adviser to Ancestry and 23 and Me. "If this were a Republican right now, if this were Ted Cruz coming out here, saying he was Native American, and he was.009 (percent), you would be going insane". Warren has previously said that she checked a box to list herself as a minority in professional listings at her university from 1986 to 1995 in order to connect with "people like me".
When it comes to challenging the man who redefined the rules of American political combat, the Massachusetts Democrat, who's weighing a 2020 presidential run, is often doing it Trump's way. Trump said in a tweet.
Warren's DNA results revealed the vast majority of her ancestry is European. Deploying an obscenity, he added: "It's like Kool-Aid man saying, 'I don't actually care about Kool-Aid'".
