PROBLEM: What is the sentiment of the following document towards the entity Brad Childress ? Former Vikings coach Brad Childress  had a brief retirement â about a month â before being lured to  his  hometown team. The Bears are expected to hire  him  as an offensive consultant. SiriusXMâs Adam Caplan first reported the move.
 Childress   an Aurora native who attended Marmion Academy  spent the last five seasons on the Chiefs staff with Nagy  serving as a spread game analyst  offensive coordinator and assistant head coach last season.  Childress  has a long history as an NFL quarterbacks coach and offensive coordinator under Andy Reid with the Eagles before spending five years as the Vikings head coach.
 Childress   61  retired from the Chiefs after  they  were eliminated in the wild-card round of the playoffs. In an appearance on âThe Mully & Hanley Showâ on WSCR-AM 670   Childress  was asked if Nagy could talk  him  out of retirement.
âYou never know â  he  replied. âI never say never.â
Nagy has talked about  his  belief in quarterback Mitch Trubisky  and  Childress  was also very upbeat about the second-year quarterback.
âI think those 12 games (of starting experience as a rookie) are really going to serve  him  well â  Childress  said. âItâs not ideal that you change your coordinator  but looking at  his  aptitude and watching  him  in the seven hours we had  him  (on a pre-draft visit)   he âll jump in the (play) book   he âll know what is going on.  He  will be able to get some of the fine points  and I just think youâll continue to see  him  grow and blossom.
Now  Childress   who began  his  coaching career at Illinois in 1978  will be on board to watch Trubisky develop.

PROBLEM: What is the sentiment of the following document towards the entity Jenny Chang ? A few years ago he began working with Dr. Jenny Chang  medical director of the Lester and Sue Smith Breast Center at Baylor College of Medicine.
 Chang had performed a number of biopsies on breast cancer patients  both on those whose cancers were confined to the breast and on those whose cancers had metastasized to the brain.
 From those biopsies  Chang said she had identified a number of genetic pathways ways in which gene mutations affected the ability of the cancer to spread unique to patients who developed metastatic breast cancer.
 "But I had a lot of trouble with the data and trying to translate it into clinical practice " she said. She couldn't find her way out from beneath the avalanche of data.
 So she turned to Wong.
 Using his mathematical modeling  Wong sifted through Chang's data and the large databases of genome and clinical trial data. Out of that  he identified several candidate drugs to impair the genetic pathways that helped the cancer spread.
Chang's data and the large databases of genome and clinical trial data. Out of that  he identified several candidate drugs to impair the genetic pathways that helped the cancer spread.
 One of them  a drug named sunitinib  which treats a kidney cancer called renal cell carcinoma  emerged as the best bet. Chang then tested the drug in mice  and the study showed it prevented breast cancer from spreading to the brain.
 She has already begun a Phase II clinical trial of the drug  enrolling nine patients with metastatic breast cancer  and she is looking for more.
 "The drug is very well-tolerated by patients  and so far the trial is going very well " Chang said.
 But by using an existing drug  Chang and Wong could skip the lengthy Phase I  during which a drug is checked for safety. If Chang's tests go well  sunitinib could be on the market within a few years for metastatic breast cancer.

SOLUTION: Positive

PROBLEM: What is the sentiment of the following document towards the entity Steve Bannon ? The attempts to curtail testimony to congressional investigators became clear this week when  former White House chief strategist Steve Bannon  appeared before the House Intelligence Committee and infuriated both sides of the aisle by refusing to answer questions about  his  work during the presidential transition and in the White House.
At some points during  Bannon 's six hours of closed-door testimony   his  attorney took breaks to confer via telephone with the White House counsel's office to clarify what questions could be answered and came back with the same guidance:  Bannon  could not discuss any activities related to the transition or  his  tenure in the White House.
 Bannon 's team negotiated ground rules with the White House counsel's office the week prior to his appearance before the House Intelligence Committee  according to a source familiar with the situation.
The President's personal legal team was aware of discussions between the White House counsel's office and  Bannon 's lawyer about protecting a possible privilege claim. But it wasn't their decision  according to a person familiar with the discussions. The protection of the privilege is a matter for the White House  not the President's legal team  because it relates to the office.
Before the hearing   Bannon 's lawyer informed a staff member of Rep. Devin Nunes  the California Republican who chairs the House Intelligence Committee  that  Bannon  planned to claim executive privilege on topics beyond the presidential campaign  a source said.
But that information was apparently tightly held. "It caught me personally by surprise" that  Bannon  asserted executive privilege  said Rep. Mike Conaway  the Texas Republican leading the committee's Russia investigation.
South Carolina Rep. Trey Gowdy and Florida Rep. Tom Rooney  the other two Republicans leading the Russia probe along with Conaway  also said they weren't aware of any agreement between the White House and committee staff about the scope of  Bannon 's testimony.
"They wouldn't do that because I'd ask what I think is relevant to ask  and if you've got a legal privilege you can assert it " Gowdy said  adding that  Bannon  was in a "legally indefensible position."
As it became clear on Tuesday that  Bannon  was refusing to answer questions  the committee served  him  with a subpoena to compel  him  to divulge additional information.
But the scope of what  Bannon  was claiming was privileged shocked members from both parties.
" His  version of executive privilege is it covers the transition  the time  he  was at the White House and covers time forever " Gowdy told Fox News Wednesday. "That is no one's definition of executive privilege."
Lawmakers were also offended that  Bannon  had already divulged details about some of  his  post-campaign activities in Michael Wolff's explosive book "Fire and Fury " but then refused to discuss those events with the committee.  Bannon 's attorney also informed members that he would  in fact  answer those questions when he meets with special counsel Robert Mueller's team because executive privilege doesn't apply to Mueller's investigation.
Democrats charge that  Bannon 's appearance before the House committee marks the broadest attempt so far at using privilege to shield events that occurred from the moment Trump was elected.
Republicans haven't ruled out the possibility of holding  Bannon  in contempt  but at least one GOP member -- Gowdy -- suggested it was unlikely.
House Speaker Paul Ryan downplayed the issue of whether witnesses like  Bannon  might be abusing the bounds of executive privilege.
Still   Bannon 's stonewalling sparked a sharp warning from Conaway -- the Republican leading the House Russia probe -- to White House aides who might follow the Bannon model: "We're going to insist on getting questions we need to answer our report."
