PROBLEM: Tensions between Republicans and Democrats over the investigation of Russian involvement in the 2016 presidential election intensified Sunday  with President Donald Trump demanding to know why his campaign is under federal scrutiny while his former opponent Hillary Clinton is not.
Democratic lawmakers mostly stayed out of the Sunday fray after a week in which  Clinton 's 2016 campaign came under fresh scrutiny. The campaign funded political opposition research into Trump that helped create a highly publicized "dossier" on the Republican candidate and fueled some allegations now under scrutiny by Mueller.
It's unclear how much the  Clinton  campaign and Democratic National Committee paid for the opposition research by Fusion GPS  a Washington  D.C.  firm that conducts investigations for private clients. The  Clinton  campaign paid $5.6 million in legal fees to a law firm from June 2015 to December 2016  according to campaign finance records  and the DNC paid the firm $3.6 million in "legal and compliance consulting'' since November 2015. It's impossible to tell from the filings how much of that work was for other legal matters and how much of it related to Fusion GPS.
Trump tweeted Sunday morning that the dossier  which he called " Clinton  made Fake Dossier " could have cost as much as $12 million  although he did not explain how he reached that number.
In April 2016  an attorney representing  Clinton 's presidential campaign and the DNC hired Fusion GPS  which then hired Steele. Brian Fallon  a former spokesman for the  Clinton  campaign  said he learned about Steele and the dossier after the election. People familiar with the matter told The Washington Post that the  Clinton  campaign and the DNC did not direct Steele's activities.

PROBLEM: 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: IN OLD DRUGS RESEARCHER LOOKS FOR NEW TREATMENTS

PROBLEM: The right-leaning Saskatchewan Party chose  Scott Moe  to replace Brad Wall as party leader and the provinceâs premier.  Moe  is expected to be sworn in as premier in the coming days.
 Moe  won the race after five rounds of voting  beating out five rivals who sought to replace Wall  who is retiring after serving as premier for a decade.
 Moe  will become premier as the province struggles to end budget deficits caused by steep declines in commodity prices.
 Moe   a former provincial environment minister  has vowed to continue to fight the Liberal government plan  saying it would do nothing to reduce carbon emissions while costing Saskatchewanâs economy more than C$2 billion ($1.6 billion).

SOLUTION:
Canada's Saskatchewan chooses Scott Moe as next premier
