FLAGSTAFF, ARIZONA – Families of Native American war veterans and politicians of both major parties are criticizing President Donald Trump for using a White House event honoring Navajo Code Talkers to take a political jab at a Democratic senator he has nicknamed "Pocahontas." The Republican president on Monday turned to a nickname he often deployed for Massachusetts Sen. Elizabeth Warren during the 2016 presidential campaign to mock her claims about being part Native American. He told the three Navajo Code Talkers on stage that he had affection for them that he doesn't have for her. "It was uncalled for," said Marty Thompson, whose great-uncle was a Navajo Code Talker. "He can say what he wants when he's out doing his presidential business among his people, but when it comes to honoring veterans or any kind of people, he needs to grow up and quit saying things like that."
