Question: 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

Question: Verify if the sentiment of the following document towards the entity Boris JohnsonLabour is Negative . London (CNN) Britain's beleaguered Prime Minister Theresa May has been urged to sack  her Foreign Secretary Boris Johnson  over his handling of the Nazanin Zaghari-Ratcliffe case.
On Sunday both Labour leader Jeremy Corbyn and London Mayor Sadiq Khan called on May to fire  Johnson -- who has been under increasing pressure since Iranian state TV claimed that his statements on the plight of the British-Iranian woman imprisoned in Tehran on charges of espionage confirmed her guilt .
Writing in the Observer on Sunday  Corbyn took aim at  Johnson   calling for him to be relieved of his duties after "undermining our country" and "putting our citizens at risk."
Also on Sunday  the UK Foreign Office told CNN that  Johnson  had held a "constructive" conversation with Richard Ratcliffe  the husband of Zaghari-Ratcliffe.
 Johnson  has been on the defensive over the past week since being forced to correct remarks  he  made to a British parliamentary committee  when  he  said that Zaghari-Ratcliffe  who has been in jail since she was detained at Tehran airport in April 2016  had been teaching journalism during her visit to the country. Zaghari-Ratcliffe and her family have maintained that she was in Iran visiting family.
After  Johnson 's original comments  authorities in Iran filed further charges against Zaghari-Ratcliffe  prompting fears her five-year sentence could be extended. On Wednesday  Iranian state TV IRIB said  Johnson  amounted to an unintentional confession.
 Foreign Secretary Boris Johnson  is set to visit Iran before the end of the year.
In  his  article  Corbyn says that the "heartbreaking" case of Zaghari-Ratcliffe has left her future liberty in peril because of  Johnson 's "serial bungling."
In a blunt final paragraph  Corbyn added: "We've put up with him embarrassing and undermining our country through his incompetence and putting our citizens at risk for long enough. It's time for  Boris Johnson  to go."
Khan was similarly critical of  Johnson   his predecessor as mayor of London calling on him to "clarify the huge error he made" and help bring Zaghari-Ratcliffe back to the UK.

Answer:
no
