Trump ally Scott Brown suggests Elizabeth Warren take DNA test to prove heritage

After Elizabeth Warren accompanied Hillary Clinton today on the campaign trail in Cincinnati, Ohio, former Massachusetts Senator Scott Brown brought up the ol' not-a-Cherokee routine once again.

Brown said on a call with the RNC that Warren was not Native American, an accusation he's recycled since 2012, when the two were both vying for the same senator seat. According to Politico:

At the height of the 2012 campaign, it was reported that Warren had listed herself as having Native American roots at Harvard University. Soon, there was a full-blown campaign frenzy, Warren recalls, with Republicans demanding that she prove her Native-American roots and accusing her of getting her job at the elite university by making false claims about her personal background.

Today, Brown brought up the tired accusations, once again asking for proof, this time suggesting she take a DNA test. According to the Washington Post:

"As you know, she's not Native American," Brown, an early Trump endorser, told reporters on a conference call organized by the Republican National Committee. "She's not 1/32 Cherokee...Harvard can release the records, she can authorize the release of those records, or she can take a DNA test..."

Recently, Trump, never to miss an opportunity to question or make fun of one's race, has repeatedly called her "Pocahontas."

Never in recent politics has the topic of heritage played such a prominent role during the presidential campaign cycle, which has only just begun.
