Sen. Al Franken (D-MN) on Sunday criticized President Donald Trump for recently referring to Sen. Elizabeth Warren (D-MA) as Pocahontas during a meeting with Republican and Democratic senators.

“I would have said something,” Franken said on Sunday on CNN’s “State of the Union.”

“I’d have said, ‘Mr. President, with all due respect, that’s racist. Please stop doing that. I am on Indian Affairs. This is completely unacceptable. You really should stop doing that. It doesn’t serve anybody.’ Something like that,” he continued.

During a meeting with senators last week, Trump told Democrats,”Pocahontas is now the face of your party,” referring to Warren. Trump also called Warren “Pocahontas” during the campaign. The senator has discussed the past stories from her family about their Native American heritage.
