 As Donald Trump continues to call Elizabeth Warren "Pocahontas" for claiming Native American heritage, former Massachusetts senator Scott Brown -- who lost to her in 2012 -- is defending that line of attack. 
  
 "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." 
  
 In the 2012 race, Brown tried and, for a short time, succeeded in making a campaign issue out of Warren's claim of Native American ancestry and whether it helped her win academic positions because of affirmative action. Brown allies in talk radio called her "Fauxcahontas," and to this day, photoshopped images of Warren with a feather headdress follow her around the Internet.

 Four years ago, Warren struggled for a while with the storyline. "I still have a picture on my mantle at home," she explained at one point, "and it’s a picture of my mother’s dad, a picture of my grandfather, and my Aunt Bee has walked by that picture at least a thousand times, remarked that her father, my poppa, had high cheekbones, like all of the Indians do." 
  
 The storyline eventually backfired on Brown, especially after some campaign workers were filmed war-whooping and making "tomahawk chops" at Warren. Today, with the campaign very much in the rear-view mirror, Brown was happy to re-litigate it, suggesting ways for Warren to prove her ancestry. 
  
 "Harvard can release the records, she can authorize the release of those records, or she can take a DNA test," he said, insisting that Warren took a job that might have rightly gone to a nonwhite applicant. "It’s a reverse form of racism, quite frankly."

 He ran against Warren in 2012 
  
 (CNN) Former Sen. Scott Brown on Monday stepped into the attack dog role for Donald Trump, saying his former Senate opponent Elizabeth Warren should "take a DNA test" if she wants to prove her Native American heritage. 
  
 "She's not Native American, she's not 1/32nd, she has no Native American background, except for what her family told her," Brown told reporters on a conference call hosted by the Republican National Committee, hours after Hillary Clinton and Warren appeared at an event together. "The easy answer, as you all know, is that Harvard and Penn can release those records, she can authorize the release of those records, she can take a DNA test, she can release the records herself. There's never been any effort," Brown said. 
  
 Warren responded on Tuesday telling the hosts of ABC's "The View" that the comments were aimed at bullying her "into shutting up." 
  
 "What this is really about is can they bully me into shutting up?" she said. "Can they be nasty enough and ugly enough and throw enough in my direction that I will say 'oh' and just go back into the shadows? And the answer is nope, not happening." 
  
 Warren and Clinton appeared at a campaign event together earlier in the day, a large part of which was spent slamming Trump, the presumptive Republican nominee.

Solution:
Former Massachusetts senator Scott Brown is not letting the Elizabeth Warren Native American controversy go. For those of you who don't remember, Warren's claims of Native American ancestry made waves during the 2012 senate race (she's reportedly only 1/32 Cherokee), and Brown made sure to rail on Warren over the claim often; his supporters edited images of her to include a feather headdress, for example, or called her "Fauxcahontas." (He still lost the race to her anyway.) Brown, who has now endorsed Donald Trump for president, brought the controversy up again Monday in a conference call with reporters that was organized by the Republican National Committee, the Washington Post reports. "As you know, she's not Native American. She's not 1/32 Cherokee. She has no Native American background, except for what her family told her," Brown said, per CNN. "The easy answer, as you all know, is that Harvard and Penn can release those records, she can authorize the release of those records, she can take a DNA test, she can release the records herself. There's never been any effort." He continued to insist that she may have taken teaching jobs away from other non-white applicants: "That took away somebody who truly was a Native American and gave that opportunity to somebody who is not, and that's just not right. It's a reverse form of racism, quite frankly." (Warren had choice words for Trump Monday.)
