Before Donald Trump took the stage Wednesday at a campaign rally in Maine, Boston talk radio host Howie Carr warmed up the crowd with a schoolyard caricature to mock Sen. Elizabeth Warren’s (D-MA) heritage.

“You know Elizabeth Warren, right?” Carr asked the crowd before pounding his hand over his mouth to make a faux-war whoop.

Carr also used the opportunity to call himself a “rich guy.”

The conservative shock jock was taking a cue from Trump, who has often referred to Warren, who recently began campaigning for Democrat Hillary Clinton, as “Pocahontas,” a nickname he uses to needle the senator about her Native American heritage.

Questions about Warren’s lineage figured prominently in her 2012 Senate race against Scott Brown. Brown, who is now a Trump surrogate, recently called for Warren to take a DNA test to prove she is indeed part Native American.
