Trump took a couple of shots at Warren on Friday night, dubbing her “Goofy Elizabeth Warren.”
Trump rekindled an attack from 2012 that then-incumbent GOP Sen. Scott Brown threw at Warren over her ancestry. Born in Oklahoma, she has said she has some Native American ancestry. Trump demanded to see records proving her heritage, the same way he's repeatedly demanded to see Obama’s birth certificate to prove that he was born in the U.S.
It isn't the first time Trump has gone after Warren over her ancestry. "She’s got about as much Indian blood as I have," Trump told New York Times columnist Maureen Dowd in March. "Her whole life was based on a fraud. She got into Harvard and all that because she said she was a minority."
Warren noticed Trump's Friday night volley, and held no punches in her reply.
Warren even co-opted Trump’s signature -- "Sad!" -- but refashioned if for her own feelings about the real estate mogul.
The Friday night spat comes just days after Warren slammed Trump following his win in the Indiana primary. “Trump has built his campaign on racism, sexism and xenophobia,” she wrote on Facebook, calling on voters from all parties to unite against Trump:
What happens next will test the character for all of us — Republican, Democrat and Independent. It will determine whether we move forward as one nation or splinter at the hands of one man’s narcissism and divisiveness. I know which side I’m on, and I’m going to fight my heart out to make sure Donald Trump’s toxic stew of hatred and insecurity never reaches the White House.
UPDATE: 10:30 p.m. -- Trump called Warren a "goofus" at a rally in Eugene, Oregon.
Editor's note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims -- 1.6 billion members of an entire religion -- from entering the U.S.
CORRECTION: A previous version of this article misstated the year that Scott Brown attacked Warren for her ancestry. It was 2012, not 2002.
