Protesters had to remind Sen. Elizabeth Warren, D-Mass., not to overlook Native Americans as she listed groups of people she claims lack power in politics. "I am angry because of everyone who has lost power," Warren said at a Thursday demonstration against Supreme Court nominee Brett Kavanaugh in Washington, D.C. Warren, a possible 2020 Democratic presidential contender, evoked African-Americans, Latinos, and members of the LGBTQ community as examples before some people in the crowd shouted out "Native Americans."
