answer:
yes


question:
Verify if the sentiment of the following document towards the entity James Comey is Positive . Wray's predecessor  James Comey  was fired by Trump in May amid the ratcheting tensions of a criminal probe into the president's former national security adviser  Michael Flynn. At the time  Trump called Comey a "showboat" and a "grandstander."
That approach  though  is a subtle rejection of some of  Comey 's most controversial decisions.  Comey  famously held a news conference in July 2016 to announce  he  would not recommend any criminal charges in the probe of Clinton's use of a private email server when  she  was secretary of state. Then in October of that year  less than two weeks before the presidential election   he  sent a letter to Congress informing them the FBI was investigating new emails in the case.
Both moves were significant departures from normal Justice Department procedure  and Clinton and her supporters blame  Comey  for costing her the election.
 Comey 's firing shocked the FBI's workforce. In the aftermath  many employees posted pictures of  him  at their desks or other workspaces.
"In some offices  you'd go in and it was just  ' Comey    Comey   Comey' everywhere " said one law enforcement official. "There's still a lot of that  but not as much."
answer:
no


question:
Verify if the sentiment of the following document towards the entity Bernie Sanders is Negative . Bernie Sanders , it is often noted , has never met a free trade deal that he liked . 
What I ca n't tell is whether Sanders simply does n't understand this , or does n't care . 
Sanders : Well , if he thinks they 're bad trade deals , I agree with him . 
With those last few words , Sanders has effectively written off trade with any country that is not already rich and prosperous -- which is simply inhumane . 
It is one thing to argue that we should not do business with nations that actively manage or manipulate their currencies , as Sanders sometimes does , since exchange rates are supposed to be the market 's main mechanism for balancing trade .
answer:

yes
