[EX Q]: 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.”

[EX Q]: Verify if the sentiment of the following document towards the entity John F. Kennedy is Neutral . BOSTON (Reuters) - More than half a century after  U.S. President John F. Kennedy  was struck down by an assassinâs bullet in Dallas  Texas  the United States is due on Thursday to release the final files on the investigation into the killing that rattled a nation.

Academics who have studied  Kennedy âs slaying on Nov. 22  1963  said they expected the final batch of files to offer no major new details on why Lee Harvey Oswald gunned down the first and only Irish-American Roman Catholic to hold the office.
They also feared that the final batch of more than 5 million total pages on the  Kennedy  assassination held in the National Archives will do little to quell long-held conspiracy theories that the 46-year-old presidentâs killing was organized by the Mafia  by Cuba  or a cabal of rogue agents.
Thousands of books  articles  TV shows and films have explored the idea that  Kennedy âs assassination was the result of an elaborate conspiracy. None have produced conclusive proof that Oswald  who was shot dead a day after killing Kennedy  worked with anyone else  though they retain a powerful cultural currency.
âMy students are really skeptical that Oswald was the lone assassin â said Patrick Maney  a professor of history at Boston College. âItâs hard to get our minds around this  that someone like a loner  a loser  could on his own have murdered  Kennedy  and changed the course of world history. But thatâs where the evidence is.â

In 1992  Congress ordered that all records relating to the investigation into  Kennedy âs death should be open to the public  and set a final deadline of Oct. 26  2017 for the entire set to be made public.
 Kennedy âs assassination was the first in a string of politically motivated killings  including those of  his  brother Robert F. Kennedy and civil rights leader Martin Luther King Jr.  that stunned the United States during the turbulent 1960s.  He  remains one of the most admired U.S. presidents.

[EX Q]: Verify if the sentiment of the following document towards the entity Saad al-Hariri is Neutral . BEIRUT (Reuters) - Lebanon believes  Saad al-Hariri  is held in Saudi Arabia  from where  he  resigned as prime minister  two top Lebanese government officials said  amid a deepening crisis pushing Lebanon onto the frontlines of a power struggle between Saudi Arabia and Iran.

In a televised statement indicating deep concern at  Hariri âs situation   his  Future Movement political party said  his  return home was necessary to uphold the Lebanese system  describing  him  as prime minister and a national leader.
 Hariri âs shock resignation  read out on television from Saudi Arabia  came as a shock even to  his  aides and embroils Lebanon further in a regional contest between Riyadh and Tehran.
 Hariri âs exit fueled wide speculation that the Sunni Muslim politician  long an ally of Riyadh  was coerced into stepping down by Saudi Arabia as it seeks to hit back against Iran and its Lebanese Shiâite ally Hezbollah.
In his resignation speech   Hariri  denounced Iran and Hezbollah for sowing strife in Arab states and said  he  feared assassination.  His  father  a veteran former prime minister  was killed by a bomb in 2005.
âKeeping  Hariri  with restricted freedom in Riyadh is an attack on Lebanese sovereignty. Our dignity is his dignity. We will work with (foreign) states to return him to Beirut â said the senior Lebanese official  speaking on condition of anonymity because the government had yet to declare this position.
Saudi Arabia says  Hariri  resigned because Hezbollah  which was included in  Hariri âs coalition government  had âhijackedâ Lebanonâs political system.
 Hariri  aides had until Thursday denied  he  was under house arrest but took a dramatically different tone after a meeting of the Future Movement convened at Haririâs Beirut residence on Thursday.
 Hariri âs aunt  Bahia  sat next to Siniora as he read the statement. The party stood behind his leadership  it said.
 Hariri  came to office last year in a political deal that made the Hezbollah-allied Christian politician Michel Aoun head of state and produced a coalition government grouping most Lebanese parties including Hezbollah.
Saudi Arabia blessed the government at the time  but has been fiercely critical of the Hariri-led government since  he  stepped down  saying it failed to act against Hezbollah  whose guerrilla army is far more powerful than the weak state.

Saudi Arabia had wanted  Hariri  to take a tougher stance toward Hezbollah  and  he  failed to do so  the fourth source said. â He  was functioning as if it is business as usual  so the Saudis had to accelerate the process and to force a resignation.â
 Hariri  flew to Saudi Arabia last Friday.
The top Lebanese government official  speaking on condition of anonymity  said: âLebanon is heading toward asking foreign and Arab states to put pressure on Saudi Arabia to release Prime Minister Saad al-Hariri.â
