"An Extended Rebuttal of Trump, Who Has Appropriated the Story of a Native American Hero to Use as a Slur"

"Warren's move to more publicly address the issue had some similarities to former president Barack Obama's 2008 campaign speeches about race—which followed criticism of his ties to the controversial former pastor Jeremiah Wright—and to Mitt Romney's 2007 speech about his Mormon faith. But Warren's speech also appeared to be an attempt to defuse the controversy before it came under the full glare, if she runs, of a national presidential campaign.
"Her speech also doesn't come without significant risks in a toxic political environment and one that could provide Trump with another opportunity to criticize her. It was also a challenge to her many critics, who have pointed to her claims of Native American heritage as a sign that she can't be trusted.
"Warren has often been reluctant to tackle the touchy issue, but she spoke with force and emotion on Wednesday."
