U.S. Senator Elizabeth Warren has released a DNA test that shows “strong evidence” she has Native-American heritage, rebutting President Donald Trump’s ridicule of her as “fake Pocahontas." She said last month she would take a “hard look” at running for the Democratic nomination to challenge Republican Trump in 2020. She and Trump clashed frequently through the 2016 presidential campaign and Trump has cast aspersions on her claim to Native-American ancestry. After he teased that he would make her take a DNA test, which he doubted would verify her claim, Trump was asked about this news to which he simply responded "Who cares?"
