Example Input: Verify if the sentiment of the following document towards the entity Medvedev is Positive . Russia's catastrophic wildfires this summer have demonstrated the need to reform the nation's forest protection legislation and the state forestry agency  President Dmitry Medvedev said Wednesday.
 The remarks appeared to reflect Medvedev's desire to take a higher profile on economic and domestic policy issues presently controlled by Prime Minister Vladimir Putin -- though Medvedev stopped short of an open challenge to his powerful predecessor and mentor.
 Putin has taken a highly visible lead in efforts to combat the fires  visiting affected areas and even taking a seat in a firefighting plane while Medvedev was chairing dull official meetings. Many political commentators perceived Putin's action as a sign of his intention to reclaim the presidency in 2012 and a clear warning to Mevedev to stand by.
 Medvedev indicated Wednesday that the prime minister's move to take direct control of the forestry agency  Rosleskhoz  could be insufficient to properly protect the nation's forests in the future.
 "If it's more convenient to work that way  you are welcome " Medvedev told a government meeting focused on forests. "But if it proves insufficient  I reserve the right to radically change those structures."
 He said the blazes had shown that the current law and the existing official structures can't properly protect the forests.
 "It's quite obvious that the legal base and the organizational structure that we have don't fit the purpose " Medvedev said in televised remarks.
 The president also said that the need for changing the current forest legislation also must be carefully analyzed.
Putin and Medvedev both have said they would decide later who will run for president.
 Medvedev avoided any direct criticism of Putin  but said Wednesday the 2006 law had left most of the nation's forests without due oversight.
 He also seemed to defy Putin on another issue -- the construction of a new highway northwest of Moscow that would destroy a forest near the town of Khimki. Putin's Cabinet has continued to support it despite growing public opposition.

Example Input: Verify if the sentiment of the following document towards the entity Donna Brazile is Negative . Sheâs been attacked by many of her former allies for airing dirty laundry in public  but  former Democratic National Committee Chairwoman Donna Brazile  took no prisoners Monday night in Chicago  telling a crowd  âMama has to eat!â
Excerpts from Brazileâs new book  in which she revealed that she at one point considered replacing Hillary Clinton with Joe Biden in the 2016 presidential campaign  and argued that a deal the Clinton campaign made to help get the national party out of debt gave Clinton unfair leverage in her primary race against Bernie Sanders  created a firestorm among Democrats last week. They also made  Brazile  an unlikely hero for Republicans  including President Donald Trump.
 A combative Brazile  referred repeatedly to  herself  in the third person and hardly let moderator Fred Hochberg get a word in edgewise  sassing her former employer CNN (âWhat you have to do now on TV is insult the other personâ); the president (âunfitâ); and âarrogantâ Clinton campaign staffers who âdisrespectedâ her (âI donât have to give anyone any kisses â Iâm 57 years old. ... Iâm not Patsy the slave!â).
But  Brazile  said  she  has a right to make money after quitting several well-paid jobs to work for the party. Many of those attacking  her  are political consultants who are upset  she  cut them from the party payroll  describing  her  book as âa wake-up callâ for the âconsultant class.â
âIâm not gonna get any Christmas presents â  she  said. âThatâs OK. I make my own gumbo!â

Example Input: Verify if the sentiment of the following document towards the entity John Grisham is Negative . CES is in full swing  and there is a particular buzz about the intersection of tech and healthcare through a very unexpected source in  best-selling author John Grisham (The Firm  The Client) .  Grisham  is applying  his  enviable skills to the powerful intersection of tech and healthcare and potentially about to turn it on its ear.
 Grisham  spoke from one of the CES stages about the growing public interest to  his  recent ebook  The Tumor which describes how a revolutionary  new medical technology called focused ultrasound could transform the treatment of serious medical disorders by curing with sound. The fictional story follows the plight of a young father who is diagnosed with a lethal brain tumor and begins a painful battle. Yet the treatment method and the tech behind it is not only very real but something which with  Grisham  is now deeply involved.  He  gave a candid interview about the scope of  his  work with this potentially game-changing move in healthcare  along with Dr. Neal Kassell  founder and chairman of the Focused Ultrasound Foundation (FUSF) and a former neurosurgeon who provided the medical and technical consulting for the book.
Prior to taking the stage at CES Grisham told me that Kassell approached  him  about being on the board of FUSF but that respectfully declined  several times. "Prior to my current involvement  I knew essentially nothing about the medical field. My usual focus is on legal matters and social injustice. So I was lukewarm  to say the least "  Grisham  said. However  as both  his  mother and  his  sister were diagnosed with cancerous tumors   he  began to see how the research that FUSF does could help millions of people facing the same diagnosis worldwide. FUSF's mission is to bring the technology that enables a lower cost method to destroy tumors with out-patient  ultrasound options and eradicate such terminal illness  where possible. Naturally  such continued research and development of this technology is expensive.
"So as I was on the board  I thought one of the best ways I could help would be to raise money "  Grisham  explained. FUSF has an annual operating budget of $10 million with 65% of that needed for research  itself. "We needed to raise awareness. Naturally  you do that through telling a story. I know how to do that." So  he  began to work with Kassell to write The Tumor with Kassell providing the deeply medical insights. After about a year  the book was ready and the Foundation it published. They decided to offer it for free and Jeff Bezos CEO of Amazon permitted them to distribute the book via the platform at this price point given its link to social good.
