Feud Between President Trump and Senator Warren Reignited

Last Thursday, President Trump renewed his attacks against Senator Warren at a campaign rally in Montana, calling her "Pocahontas" and challenging her to take a DNA test to prove her heritage claims. Senator Warren responded on Sunday, calling the President a bully, and saying that Trump wants the country talking about "anything other than what's going on in the Trump administration."
