Question: Verify if the sentiment of the following document towards the entity Elizabeth Warren is Positive . Six years ago  the contested story of Sen. Elizabeth Warren's Native American heritage began its rise from local newspapers to national headlines  and eventually into presidential speeches and Twitter feeds.
On Wednesday   Warren  raised the subject  herself  — not budging from the story  she  has relayed for years — in a surprise speech to the National Congress of American Indians.
And I want to make something clear. I respect that distinction. I understand that tribal membership is determined by tribes — and only by tribes. I never used my family tree to get a break or get ahead. I never used it to advance my career ”  Warren  said.
The stories  she  grew up with are real   Warren  said  which is what  she  has regularly said on the matter. There is no known documentation of  Warren ’s Native American ancestry (though somewhere in the 2012 back-and-forth a genealogist estimated  Warren  was 1/32 Cherokee)  but the senator has steadfastly argued that she was raised on stories of Native American family members and this is what she knows to be her family's heritage.
 Warren  has been adamant about the pride  she  feels to be Native American — though the topic has dogged  her  politically. At the event  a days-long policy summit in Washington  D.C.  attended by a wide range of tribal leaders   Warren  described  her  dedication to fight against the “country’s disrespect of Native people.”
“For far too long  your story has been pushed aside  to be trotted out only in cartoons and commercials ”  she  said.
 Warren  used President Donald Trump’s nickname for  her   Pocahontas  as an example of the disrespect.
The questions began  however  four years earlier. At the time  the Republican incumbent senator of Massachusetts  Scott Brown  was up against  Warren  for the senate seat. He brought up  Warren ’s undocumented claim of Native American heritage in a debate and asserted that she’d been using it to get ahead in jobs.
The main evidence of  Warren ’s use of  her  heritage was to list  herself  as a minority in a legal directory in the 1980s and 90s.  She  was later described as the only minority female faculty member at Harvard Law School in a 1996 survey report on diversity.
 Warren  has repeatedly denied that  she  ever used it to advance  her  career. “All I can say is  I busted my tail as a teacher. I am qualified for my job "  she  said in 2012.
On  her  family   Warren  said  “They’re gone  but the love they shared  the struggles they endured  the family they built  and the story they lived will always be a part of me. And no one — not even the president of the United States — will ever take that part of me away.”

Answer: yes


Question: Verify if the sentiment of the following document towards the entity Reba McEntire Reba is Negative . The next Colonel Sanders is giving the character a little bit of "country music flair." KFC has picked  singer Reba McEntire  to play the founder of the fried chicken chain  the first female celebrity in the role.
In commercials starting next week   McEntire  dons the Colonel's famous white suit and black tie  but with a twist.
 McEntire 's outfit has fringe on the back  and a glittery shine  giving the getup "a little bit of the country music flair " she told The Associated Press in an interview.  McEntire  sings on stage as the Colonel  with a white wig and white facial hair.
"I thought the transformation was really funny " said  McEntire   who will appear in the ads until the end of April. "I got a big kick out of it."
A rotating cast of famous names have portrayed the Colonel since 2015  but  McEntire  is the first famous female to do it  and the first musician.  She  may also be the first woman in KFC's nearly 90-year-history to depict the Colonel. The company said the "best historical minds at KFC" could not remember a woman having stepped into the role.
 McEntire  was approached about doing so in December. "I said 'Holy smokes!' "  McEntire  told The AP. "KFC has been a part of my life forever."
 Reba McEntire  can cross playing KFC's Colonel Sanders off  her  bucket list.
KFC said it picked  McEntire  because of  her  Southern roots  and to help promote its new Smoky Mountain BBQ  which combines fried chicken with a taste of barbeque.  McEntire  said  she 's eaten at KFC all  her  life  since  her  days growing up in Oklahoma.
 She  sings in the ad  in a tongue-in-cheek approach: "I'm Colonel Sanders  the same as always "  McEntire  sings. "I'm definitely not a woman."  McEntire  also appears as  herself  in the commercial  as an audience member.
