In a subsequent post minutes later, Trump wrote: "Now that her claims of being of Indian heritage have turned out to be a scam and a lie, Elizabeth Warren should apologize for perpetrating this fraud against the American Public".
The genetic results released Monday provide some evidence of a Native American in Warren's lineage, though the ancestor probably lived six to 10 generations ago.
Hoskin said the tests can not even reliably determine lineage among North or South American tribal groups.
Tucker Carlson said Tuesday that the "frenzy to oppose all that Trump endorses" led Democrats to "tar" Justice Brett Kavanaugh as a racist and make other untimely decisions.
Fox News Radio's Guy Benson and Marie Harf debate what the results of Senator Warren's DNA test mean. But even if it only helped her network, or get an interview, it was a cheat. She continued, "I think of her as a smart woman and not getting into petty politics, and that's exactly what this is". "That's why the wholesale acceptance of Elizabeth Warren's DNA-based claim to an indigenous identity is so harmful - because it is an existential threat to tribes themselves".
Warren said last month she would take a "hard look" at running for president against Trump in 2020, and her aggressive move to put her ancestry controversy behind her seemed to be another sign she will take the plunge.
"As the daughter of Iranian immigrants who worked tirelessly to achieve the American dream, I can tell you that being of Iranian heritage is not awful", said Eskamani.
Until now, Warren said she had nothing to back up her claim except family lore, stories told within her family in Oklahoma and passed along through generations.
Warren responded with a tweet accusing Trump of racism, and clarifying the distinction between DNA and tribal citizenship.
Trump also claimed that Warren would not have been hired as a Harvard law professor if not for claiming to be a "person of color".
Having provided the results to American newspaper the Boston Globe yesterday, Warren now has conclusive proof of her Native American ancerstry.
He said "using a DNA test to lay claim to any connection to the Cherokee Nation or any tribal nation, even vaguely, is inappropriate and wrong".
Democrats, meanwhile, were irked over her decision to signal her 2020 presidential intentions just three weeks before the critical November 6 midterms, faulting her for shifting the focus away from the candidates while providing political cannon fodder for Republicans.
"I'll only do it if I can test her personally. You better read it again", and later qualified that his charity offer would only apply if Warren were to win the 2020 president general election nomination. "This is not something I would enjoy doing either".
