Massachusetts Senator Elizabeth Warren has released a DNA test that provides “strong evidence” of partial Native American lineage in her family tree dating back six to 10 generations. Warren released the test results Monday along with a video about her family heritage. The move comes in response to President Trump’s mocking of Senator Warren’s previous statements on her Native American heritage. Trump has repeatedly referred to her as “Pocahontas,” including as recently as last week. Last month, Warren said at a town hall meeting that she would “take a hard look” at a 2020 presidential run after the midterms.
