Republican Sen. John McCain of Arizona is tweeting that President Donald Trump's "politicizing" of a ceremony honoring Native American veterans was "an insult to their sacrifice."
McCain doesn't cite the president by name in his tweet Tuesday. He says the nation owes a debt of gratitude to the Navajo Code Talkers for helping secure victory over tyranny and oppression during World War II.
He then adds: "Politicizing these genuine American heroes is an insult to their sacrifice."
During a White House event Monday, Trump revived past mocking comments he's made about Sen. Elizabeth Warren for claims she made about being part Native American.
Trump said: "We have a representative in Congress who they say was here a long time ago. They call her Pocahontas. But you know what, I like you."
