The president of the Navajo Nation ripped President Trump for referring to Sen. Elizabeth Warren as “Pocahontas” during a White House ceremony honoring Native American war heroes as “unnecessary” and “culturally insensitive.”

Asked during an interview on CNN if he took Trump’s comments about the Massachusetts Democrat as a slur, Russell Begaye said he did.

“I feel that the way it was used, yes it was. Pocahontas is a real person, not a caricature, not something or someone made up,” he said on CNN’s “New Day.” “This is a person, a young lady, a Native American woman that played a critical role in the life of this nation. And to use that person in that way is unnecessary and is culturally insensitive.”

The president made the remark as the White House honored three Navajo war heroes who helped the US Marines develop a secret code during World War II.

“You were here long before any of us were here,” Trump told them. “Although we have a representative in Congress who they say was here a long time ago. They call her Pocahontas.”

Trump began mocking Warren, who claims a Native American heritage, as “Pocahontas” while campaigning during the 2016 presidential election.

Begaye said Trump should have never uttered the word in front of the Native Americans.

“This was a day to honor them,” he said. “And to insert something like that — the word Pocahontas as a jab to a senator — that belongs on the campaign trail, that doesn’t belong in the room where war heroes are being honored.”

Sen. John McCain also lashed out at Trump for “politicizing” an event that should have been used to celebrate their accomplishments.

“Our nation owes a debt of gratitude to the Navajo Code Talkers, whose bravery, skill & tenacity helped secure our decisive victory over tyranny & oppression during WWII. Politicizing these genuine American heroes is an insult to their sacrifice,” the Arizona Republican tweeted.

Trump hosted the Native American heroes beneath a painting of Andrew Jackson, the former president who in 1830 signed legislation to relocate more than 60,000 Native Americans from Georgia to Oklahoma.
