REUTERS/Brian Snyder Donald Trump took aim at one of the most progressive members of the US Senate on Friday evening, tweeting that he hopes Hillary Clinton selects "goofy Elizabeth Warren" as her running mate so he can defeat them.

Warren, a Democrat from Massachusetts, posted a flurry of critical tweets about Trump on Tuesday following his Indiana win, declaring that she would "fight [her] heart out" to ensure that Trump's "toxic stew of hatred & insecurity never reaches the White House."

On Friday, Trump mocked Warren's controversial claim that she is part Native American. It first drew scrutiny during her 2012 Senate race, when it was reported that she had declared at Harvard that she had Cherokee and Delaware Indian ancestry, according to Politico.

Trump called Warren a "fraud" and suggested that her ancestry records be checked.
