President Trump on Monday referred to Sen. Elizabeth Warren (D-Mass.) as “Pocahontas” at an event honoring Native American “code talkers” who served in World War II.

“You were here long before any of us were here,” Trump said, standing beneath a portrait of former President Andrew Jackson. “Although we have a representative in Congress who they say was here a long time ago. They call her Pocahontas.”

Turning to the veterans, Trump said “but do you know what? I like you.”

The president made the remark in the Oval Office standing beside three Navajos who helped the U.S. Marine Corps develop a secret code during the Second World War.
